Industrial semiconductor lasers and their application potential

In recent years, laser technology has developed rapidly and is familiar to people. Its application fields mainly include industrial manufacturing, national defense, communications, medical cosmetology, consumer entertainment, etc. For different fields and scenes, the wavelength, power, beam, intensity, pulse width and other properties of the laser are not the same, the laser can be divided into crystal luminous solid laser, gas laser, fiber laser, semiconductor laser, chemical liquid laser and so on.

Semiconductor lasers: a promising technology

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. Therefore, many experts believe that the semiconductor laser will become the most promising laser.

Semiconductor lasers used in industrial processing are generally divided into direct output and fiber coupling output modes. Direct output semiconductor laser beam is rectangular, easy to be affected by back reflection, dust and other factors, the price is slightly cheaper; The fiber coupled semiconductor laser beam is round, can avoid the interference of back reflection and dust, and can integrate the robot to achieve flexible processing, but the price is expensive. Compared with fiber laser, semiconductor laser beam quality is almost, so rarely used for cutting, semiconductor laser is the most widely used in marking, metal welding, cladding, hardening, and plastic welding and other applications.

Semiconductor lasers are widely used

In welding and cladding, semiconductor laser has a great use. The application of semiconductor laser in brazing of automobile body in white has been very mature, and has been assembled in the production line of Volkswagen, Audi and some other models. General steel welding is also an important application of semiconductor laser, in addition to hardware processing, shipping, rail transportation is also an important application field. In recent years, the new blue semiconductor lasers have excellent application potential in copper materials, motors, cells and other products. Laser cladding plays an important role and value in the repair and renovation of core metal parts in heavy industry and construction machinery industry. Hydraulic shaft such as mining machine, drilling screw, motor rotor, bearing, turbine blade and so on, the operation in the long run will appear different degree of wear and replace as it's a pity, and high cost, increase the coating using laser cladding bounced back at this moment, is the most economical way, the semiconductor laser is the most popular laser laser cladding.

Semiconductor laser professional cooling equipment
