激光晶体（laser crystal），可将外界提供的能量通过光学谐振腔转化为在空间和时间上相干的具有高度平行性和单色性激光的晶体材料。是晶体激光器的工作物质。
作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：
晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
g. a skinny disk. As A different illustration, Q-switched lasers reach a better inhabitants density within the higher laser level and they are for that reason more delicate to quenching effects and Electricity transfer procedures; hence, a reduced doping density is often appropriate for these devices. For high-ability lasers, lessen doping densities tend to be accustomed to Restrict the density of heat generation, Whilst thin-disk lasers get the job done finest with really doped crystals. Several laser merchandise do not get to the entire effectiveness possible mainly because these types of details have not been effectively labored out.
The host crystal is considerably more than just a way to fix the laser-active ions at specific positions in Area. Quite a few Attributes of your host content are important:
热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。

GWU-Lasertechnik has a lot more than thirty a long time of expertise in distributing laser crystals. Opt for GWU to benefit from our vast understanding As well as in-subject working experience!
There may be a wide array of crystalline media, which may be grouped in accordance to big atomic constituents and crystalline Laser Crystal structures. Some important groups of crystals are:
人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
