Inventory Of Several Lasers Commonly Used In Industrial Production
- Jun 22, 2017 -

At present, fiber lasers play a very key role in the field of industrial processing, especially in high-power laser processing. Different types of lasers have differences in characteristics, so their applicability varies in different industry areas.


Then let's distinguish between the types and applications of lasers. According to the working material division, the laser can be divided into gas lasers, including CO2 lasers, he-ne lasers, liquid lasers with liquid dyes as pump optically, solid-state lasers, Nd:yag, Nd:yvo4, YB:YLP, etc., semiconductor lasers and so on. According to the working method, it can be divided into continuous laser and pulse type laser.


From the basic working principle, a variety of lasers are much the same, including pump optically, optical resonator and gain medium three parts. In the aspect of laser marking, the commonly used lasers are YAG lamp pumped solid-state lasers, side pumped solid-state lasers, end pumped solid-state lasers, fiber lasers, CO2 lasers. As far as marking machining is concerned, many lasers are competent in this area because the processing depth and strength are not very high.


Side pump and end pump is mainly in the pump direction of the difference. CO2 Laser is a gas laser with a wavelength of 10.6 microns in the Far Infrared optical band, using CO2 gas as pumped medium.


Coupled with high voltages, self-excited conductivity is generated in thin gases, which in turn releases lasers from gas molecules. Laser technology is widely used in industry, but it makes people feel a little far away from our life. And in our daily life, in fact, many places can see the shadow of laser processing.


For example, the usual purchase of goods, see the code, clothing accessories are also a lot of laser processing, before the common CD/DVD, work often used in laser printers, laser anti-counterfeiting signs, shopping payment when the salesperson used barcode scanner and so on. In fact, the types of lasers are much more than these, and with the continuous development of science and technology, laser technology is also constantly penetrating into more areas, bringing more changes to our lives.
