As we all know, lasers are widely used today. Such as laser ranging, laser cutting, laser welding, etc. in the field of livelihood, and even in the medical field can be used to treat myopia. The main application field of laser is the military field. Whether it is laser guidance or laser weapons, laser technology is sought after by all countries.

Laser crystal is an important part of laser, and most of the active ions used are transition metal ions and trivalent rare earth ions. The matrix crystals used for laser crystals are mainly divided into oxides and fluorides. The laser crystal composed of activated ions and matrix; The following are the characteristics and application directions of several laser crystals:

In order to research and develop the laser field, there is a technology that cannot be bypassed, that is, laser crystals. Laser crystals can convert the energy provided by the outside world into highly parallel light, and are important components of crystal lasers. In short, laser crystal is the engine of all laser equipment and the core component of laser equipment. Of course, the above is just a part of the laser crystals and applications introduced by Guangbao. You can understand that if you have more knowledge about laser crystals, you can call Guangbao Optoelectronics at any time.
