The laser rod is a solid based on yttrium aluminum garnet crystal.

Ce: Nd: YAG crystal (yellow bar): For flash lamp pumped lasers, the emission spectrum of the pump lamp is a broadband successive pump, and only a few spectral peaks match the absorption peaks of Nd ions, so the usual lamp The pump uses only a small amount of spectral energy, and the power is low. Ce ions are added on the basis of Nd: YAG crystals to form Ce: Nd: YAG is to use Ce ions to absorb photon energy in the ultraviolet spectral region, and transfer the energy to Nd ions in a non-radiative transition method, and then increase In order to improve the utilization rate of the spectrum, the laser rod has high power, low threshold and good repetition frequency characteristics. In addition, it will be harmful to Nd: YAG ultraviolet radiation (long-term ultraviolet radiation will form a color center in the Nd: YAG crystal, and then reduce the laser function of the crystal) for useful use, thus resisting ultraviolet radiation, There is even no need for a special ultraviolet filter quartz sleeve. Ce: Nd: YAG is also known as yellow bar because the crystal becomes yellow after doping with Ce. It can supply Φ1-20(D)*10-140(L)mm laser rods and various slat components, with Nd concentration of 0.6~1.1at.% and Ce concentration of 0.03~0.4at.%.
