Compared with traditional machining, green laser pen machining has the advantages of no tool wear, flexible cutting shape, controllable edge quality, higher precision, and lower operating costs. Due to its excellent performance, lithium batteries are widely used in consumer electronics, automotive and energy markets, and innovation in production technology is particularly important. The production steps for lithium batteries are typical "roll-to-roll" processes that require two processing steps - making the film into individual cells, and assembling the individual cells into a battery system. Solid-state laser cooling is very similar to atomic high power laser pointer cooling. The fundamental difference is that there are a large number of atoms interacting between solids to form atomic chains. The atoms are fixed in the lattice. The kinetic energy of photon absorption is no longer isolated atoms, but a large number of atoms collectively vibrating. In the form of lattice vibrations (phonons), thermal energy can provide the additional energy and momentum needed for fluorescence upconversion. Compared to laser cooling atoms, the conditions for laser cooling solids are more stringent.
Energy in the opposite direction of the green laser pointer
Welding technical requirements of plastic green astronomical laser welding plastic: the material in the hot zone requires good light absorption of the laser; the material that does not belong to the heat dissipation part requires good light transmittance, especially on two thin plastic parts. . Thermoplastics include amorphous plastics and semi-crystalline plastics. Laser weldable plastics are thermoplastics. In theory, all thermoplastics can be laser welded. Generally, adding heat to the water-absorbing plastic area can achieve the purpose.
When irradiated with a green laser pointer, the principle is first used to cool atoms and rarefied gases. The beam energy is slightly less than the energy required for the atomic transition of one gas atom (such as rubidium gas), when the atoms move faster than the green laser pointer atoms in the opposite direction than the other direction. The energy of the laser light is felt higher, so the scattered photons of these atoms and the low energy laser photons absorbed by the high energy are known as the Doppler effect. Another application that utilizes UV lasers to achieve small beam size and low stress characteristics is drilling, including through holes, microvias, and blind burrs. UV-green laser systems drill through substrates by focusing a vertical beam directly through the substrate. Depending on the material used, holes as small as 10 μm can be drilled.
