532 nanometers (nm) or green wavelengths can control the heat balance of these small and highly conductive components while ensuring that they are not overheated or underheated.

A laser pointer is a tool that uses a laser as an indication.Can indicate the length is far, can replace the pointer and other indicating tools, can also be used in the display of slides, such as PPT, as an indication.Current laser Pointers are mostly red.

There is only one pump module inside the laser, it is called a single-mode laser, and multiple pump modules are combined together to allow multiple pump beams to enter the active fiber through a beam combiner, so that higher power can be obtained.

Lasers have many properties: First, lasers are monochromatic, or single-frequency. Second, laser light is coherent light. The characteristic of coherent light is that all its light waves are synchronized, and the whole beam of light is like a "wave train". Again, the laser is highly concentrated, which means that it has to travel a long distance before it becomes dispersed or converged.

Thick and thin plates of automobile body, automobile parts, lithium batteries, pacemakers, sealed relays and other sealed devices, as well as various devices that do not allow welding pollution and deformation. Currently used lasers are YAG lasers, CO2 lasers and semiconductor pumped lasers.

the basic attachment of the laser is fixed, that is, the working substance, the excitation source, and the optical resonator are composed of three parts. The pump source provides the light source for the laser, and the gain medium (also known as the working substance) absorbs the energy provided by the pump source and amplifies the light. The resonator is the loop between the pump light source and the gain medium. The resonator oscillates and selects the mode to output the laser.

The industrial semiconductor laser has great market potential because of its very high conversion rate, compared with the solid laser, the semiconductor laser can reach 45%, many experiments can reach 70%. This means that the output of the same power laser beam, semiconductor laser more electricity saving, electricity saving is to save money, for users to save money equipment products will certainly be popular.

Researchers are developing a non-invasive method to measure blood flow to the brain using infrared spectroscopy.These include a new paper fluorescence tool that can image brain activity in 3D; And a wearable cap with a built-in infrared laser that even babies can wear to detect brain damage.

Microwelding technology provides excellent joint integrity, long service life and good electrical conductivity.532nm, or green light wavelength, which will quickly diffuse heat from the welding joint.

The green laser​ is used as the recording light to record three holograms at the same time, and then the red, green and blue lasers read out the corresponding holograms respectively, and the three RGB images are synthesized into a three-dimensional color hologram image.
