Here are the types and applications of lasers:
According to the working substance, lasers can be divided into gas lasers, including CO2 laser, HE-NE laser, etc.Liquid laser with liquid dye as pump source;Solid state laser, Nd: YAG, Nd: YVO4, Yb: YLP, etc.Semiconductor lasers and so on.According to the working mode, it can be divided into continuous laser and pulse laser.
In terms of laser marking, the commonly used lasers are YAG lamp pumped solid-state laser, side-pumped solid-state laser, end-pumped solid-state laser, optical fiber laser and CO2 laser.In terms of marking processing, many lasers are competent in this respect because of the low processing depth and intensity.Side pumps and end pumps are mainly in the direction of the pump.
CO2 laser is a gas laser with a wavelength of 10.6 micron in far-infrared optical frequency band. CO2 gas is used as pumping medium.This, coupled with a high voltage, creates a self-excited conduction in the rarefied gas, which in turn causes the gas molecules to emit a laser.
Laser technology is widely used in industry, but it makes people feel a little far from our life.In our daily life, in fact, many places can see the shadow of laser processing.For example, when you usually buy goods, see the mark code, clothing accessories are also a lot of laser processing, before the common CD/DVD, the work of the laser printer, laser anti-counterfeiting mark, shop assistants use barcode scanner and so on.
In fact, the types of lasers are far more than these, and with the continuous development of science and technology, laser technology is also constantly penetrating into more fields, bringing more changes to our lives.
