Scientists are studying how to use ultrashort pulse (also known as ultrafast) laser pointers to etch microstructures into thin glass. There may be applications in analytics (lab-on-a-chip), especially in the field of electronics and consumers. A special method of irradiating the glass with an ultrafast laser increases the sensitivity of the glass to subsequent wet chemical etchings by a factor of 1000. This means that a laser beam with a diameter of a few microns can pass through a glass block and be etched through a thin tube through a glass volume. If you are a laser pointer or DIY enthusiast, a laser engraving machine can be a very useful tool for you.

This method can be used to create minimal holes, etch a complete microfluidic system into glass, or make incisions with very high surface quality. There are some questions that need to be answered before this phenomenon becomes an industrial process. The answer to these questions is the Femto Digital Photon Production Joint Research Project, funded by the Federal Ministry of Education and Research (BMBF; Bonn, Germany). Since 2014, representatives of RWTH Aachen University (Aachen, Germany) and Fraunhofer Institute for Laser Technology (ILT; Aachen, Germany) have been studying the use of ultrafast laser pulses in the processing of transparent materials6 We have cooperated with the company. A new phenomenon. .. They have developed selective laser etching (SLE). It has been tested on a wide variety of glass materials such as quartz glass, sapphire, borofloat 33, and Corning Willow. Many people use laser pointers to repel pests and birds, especially crows.

This method is very environmentally friendly. In Borofloat 33, the etching selectivity between the laser structured and unstructured regions reaches 1000: 1 and in willow glass it reaches about 100: 1. In the next phase of the project, experiments will be conducted at RWTH Aachen University, where complex simulations will be performed in parallel with Nonlinear Dynamics (NLD) in the Education and Research Department of the laser manufacturing process. The Chair of Optical Systems Technology (TOS) will focus on optimizing the optical system in the system. The researchers are working with three purple laser pointer laser light source manufacturers (Amphos, Edgewave, TRUMPF) and three laser pointer system suppliers (4JET, LightFab, Pulsar Photonics).

Their goal is to develop a multi-beam system for large surfaces and a small system for microprocessing. LightFab, a start-up company at RWTH Aachen University, uses SLE to manufacture 3D precision parts made of quartz glass. This laser pointer machine increases the productivity of subtractive 3D printing of glass parts for prototypes and series, and thanks to its high speed module, parts can be mass-produced in the SLE process. Project partners have seen many potential applications for this technology. For microfluidics, not only do you create channels in the glass material, but you also create nozzles and other microcomponents. Red laser pointer technology also has advantages in the drilling and cutting process. Etching allows for ablation of tension-free materials.

Laser pointer Laser cleaning is economical and reliable
Laser pointer: https://www.laserpointerjp.com/
Laser cleaning solutions combine state-of-the-art cleaning with process monitoring and online process control. Large-scale BiZirong cleaning began in Germany in the late 1990s and has been established since the technology industry was established. For example, in the United States, hundreds of devices in the automotive, aerospace, and general industries are demonstrating the potential of laser cleaning.
Green laser pointer: https://www.laserpointerjp.com/greenlaser.html
Green Laser Pointers for Industrial Parts and Surfaces Laser-based surface pretreatment is often an economical alternative to traditional component cleaning. In addition to low energy consumption, the media-free process does not require chemicals or abrasives. Therefore, light cleaning is especially sustainable and environmentally friendly. A short pulse industrial cleaning laser is used to avoid damage to the surface of the component. Various effects and surface properties can be adjusted depending on the intensity, pulse width and wavelength. It ranges from gentle cleaning to selective surface structuring. The effect of laser radiation depends on the absorption of the processed material. Powerful high-power laser pointers have many uses, including the ability to use laser pointers to repel pests, birds, and other animals, especially to repel crows.
Crow repulsion: https://www.laserpointerjp.com/3000mw-red-laser-pointer12-9.html
Metals have high reflectance for typical solid wavelengths of 1064 nm, but surface impurities and oxides better absorb laser radiation. Therefore, moderate beam intensity can be used to remove contaminants from the surface without damaging the underlying metal. When washed with light, organic and acidic oxide contaminants are effectively blown off the surface of metal parts. By enhancing the laser parameters, the metal material of the top boundary layer (typically up to 5 µm) can be modified to produce structure or roughness. One example is to improve the corrosive performance of light metals and increase the surface area by roughening. Laser beam cleaning is highly accurate and reproducible, which can significantly save the cost of industrial mass production. Current investments in blue laser pointer laser technology are usually many times cheaper than investments in wet chemical alternatives.
Blue laser pointer: https://www.laserpointerjp.com/bluelaser.html
In addition, the operating costs of high-efficiency laser machines are usually significantly reduced due to their low energy consumption (several kilowatt hours) and moderate maintenance requirements. Therefore, component costs can be significantly reduced, especially when using a large number of parts and a fully automated process. The flexibility provided by laser cleaning makes it suitable for a variety of industrial applications such as pretreatment of joints and welded joints, accurate removal of coating contours such as providing electrical contacts, and paint removers for adhesive pretreatment. I will. Post-treatment of welds and rust prevention of steel before varnish / cathode dip coating.
Rice University chemists use a red laser pointer laser to create graphene
Red laser pointer: https://www.laserpointerjp.com/redlaser.html
American chemist James Tour (James Tour) and his colleagues used carbon dioxide (CO 2) laser scribing to blacken the thin-film laser-induced graphene (LIG) pattern of pine trees. Laser-induced graphene was discovered in rice in 2014. A previous iteration of LIG was done by laser heating the surface of polyethylene (a cheap plastic). LIG is not a flat sheet of hexagonal carbon atoms, but a form of graphene sheet with one edge attached to the lower surface while the chemically active edges are exposed to air. According to the tour, not only does every polypropylene produce LIG, but some woods are more popular than others. A research purple laser pointer team led by Rice University graduate students Ruquan Ye and Yeeu Chyan tried to use birch and oak, but the cross-linked lignocellulose structure of the pine produces higher quality graphene than wood with low lignin content. I found that it can be generated.
Purple laser pointer: https://www.laserpointerjp.com/purplelaser.html
LIG has a high conductivity of about 10Ω / square. Similar to polyimide, this process uses a standard industrial CO 2 laser and uses an inert argon or hydrogen atmosphere at room temperature and pressure. In the absence of oxygen, the heat from the laser does not burn the pine tree, but converts the surface into a graphene foam sheet bonded to the surface of the tree. Changing the laser power also changes the chemical composition and thermal stability of the resulting LIG. At 70% power, the laser produces the highest quality called P-LIG (P stands for pine). The lab takes P-LIG one step further by converting it into electrodes for breaking down water into hydrogen and oxygen and supercapacitors for energy storage. With a small laser engraving machine, you can DIY any kind of pattern you need at home.
Laser engraving machine: https://www.laserpointerjp.com/diy-tool-mini-laser-engraving.html
In the former case, they deposited layers of cobalt, phosphorus, nickel, and iron on P-LIG to create a pair of high surface area electrocatalysts that proved durable and effective. According to the tour, depositing polyaniline on P-LIG could result in an energy storage supercapacitor with usable performance indicators. You said: "There are more applications to explore." "For example, P-LIG can be used for photosynthesis of solar energy. This discovery considers how scientists can make the surrounding natural resources more functional. The tour confirms the environmental benefits of biodegradable electronics, saying, "Because graphene is a sheet of natural mineral graphite, instead of burying everything, it's on the ground with a wooden platform. I plan to bring it back. Electronic parts. "

Green laser pointer treats smoke from femtosecond laser treatment
Examples of femtosecond laser treatment include the manufacture of hard glass, thin film patterning, and electrode construction of lithium-ion batteries. Advanced laser pointer laser technology can improve the utilization of the manufacturing process. This helps to gain insight into laser smoke, a key factor affecting product quality, machine life, environmental / safety and health considerations. Ultrashort Pulse (USP) Blue Laser Pointer The laser process focuses on non-melting preparation and brings exciting new applications.
Blue laser pointer: https://www.laserpointerjp.com/bluelaser.html
Almost all advanced laser pointer technologies, from the manufacture of hard glass to thin film photomotive power patterns to electrode structures for lithium-ion batteries, rely on USP laser technology. This study was performed with a femtosecond laser with a wavelength of 1064 nm. 3 Investigate the relationship between the type of ablated material, particle size distribution and particle concentration, and specifically evaluate the difference in particle size between steel and plastic. Red Laser Pointer Aerosols produced by laser material processing are captured near the source and sucked towards the filter system.
Red laser pointer: https://www.laserpointerjp.com/redlaser.html
Engine exhaust particle size (EEPS) spectrometers are used to continuously measure particle size distribution and can measure particle size in the range of 5.6 to 560 nm. For this purpose, the sample is analyzed on the instrument. The particles in the sample are positively charged and move in the electric field towards the electrometer, where the charge is transferred-the charge is a measure of the surface area of ​​the particle. Depending on their electrical mobility, the particles reach different electrometers. The particle size distribution is calculated based on the current. In addition, the sample was removed from a laser pointer filter and examined under a secondary electron microscope (SEM) to analyze the shape of the particles. Use the LAS 260 filter system (Figure 1) to filter the original gas. The purple laser pointer system is a storage filter with F9 pleated pre-filter function.
Purple laser pointer: https://www.laserpointerjp.com/purplelaser.html
The pre-filter consists of a high surface area and a clear cross flow to extend the life of the filter. The HEPA grade H14 secondary particle filter ensures that the cleaning capacity reaches 0.005% of the total particle number. Under the air stream, activated carbon is placed to eliminate harmful gases that may be generated during laser processing. The performance of the LAS260 filter system has also been determined. To do this, keep the laser pointer stationary and use the EEPS method to measure the particle concentration of the original and purified gas.

Most fiber laser pointer welds are performed with larger multimode focused laser spots. This eliminates the problem of the weld seam being too narrow and can result in insufficient mechanical strength.
Laser pointer: https://www.laserpointerjp.com/
However, even with multimode laser points, the physical gaps between the parts are relatively small, so part edge preparation and manufacturer assembly need to be improved. These requirements increase manufacturing costs. As a means of overcoming these limitations, it is perpendicular to the weld with a beam swing (ie, a small focus, single-mode or multi-mode green laser pointer beam (rather than a simple linear motion of the beam along the desired weld). Fast scan) has been identified. Beam swing increases the beam. Effective size of keyhole welding while effectively transmitting the laser power intensity required for keyhole welding. Therefore, the beam swing can fill larger gap sizes and more reliably control welding parameters such as seam width and penetration.

Proven to produce laser welds with quality and throughput rates that meet the production requirements of automotive and electronic equipment
Blue laser pointer: https://www.laserpointerjp.com/bluelaser.html
The use of beam pendulums in single-mode or multi-mode spot welding has shown superior results compared to traditional multi-mode spot welding. A particular implementation of coherent beam control is called SmartWeld + and has several techniques over other versions of this method. Progress In particular, it includes predictable energy inputs. It can be used with an infrared (1070 nm) focused single-mode beam with a focal size of 30 µm, and the number and types of oscillation modes have been expanded to an elliptical shape. , Spiral and more complex patterns (Figure 1). These patterns can be scaled and automatically rotated to follow the weld path or contour. In some cases, it can be combined with red laser pointer output modulation by adjusting the trajectory along the micropattern. The scan speed gives you precise control over the energy distribution of the light spot or seam. This allows you to adjust individual energy inputs across different parts of the pattern or material, allowing you to define preheating, process, or cooling regions and precisely control welds. dynamic. The result is improved welding accuracy and reproducibility while minimizing heat-affected zone (HAZ) and low porosity. The examples shown here show the specific benefits of this technology.

The function of the blue laser pointer offers the possibility of welding thicker copper and other challenging materials and also improves the ability to weld dissimilar metals.

Purple laser pointer: https://www.laserpointerjp.com/purplelaser.html
Traditional infrared (IR) industrial lasers are not suitable for processing copper and many other reflective metals. This is because these materials absorb only 1% of the incident laser energy. For example, to start brazing, an infrared laser must provide 20 times the energy required to melt the material. However, once the melting begins, the copper absorbs more IR energy, causing a small local "explosion" in the molten copper. These explosions expel material from the melt, leaving holes called splashes and voids, respectively. Splashes and voids reduce the mechanical reliability and electrical fidelity of welded joints. Various laser beam exposure patterns, called "wobbles," can alleviate these problems, but they cannot eliminate them. In addition, the combination of exposure time and energy of some geometries does not produce welds. The blue laser changed the rules of the game. As shown in Figure 1, copper absorbs more than 13 times more blue light than IR. Also, even if copper melts, the absorption rate does not change much. When the blue laser begins welding, welding continues at the same energy density. This process is highly controllable and error-free, resulting in the fastest and highest quality brazing. High power lasers can be used to repel pests and crows.
