Laser crystals are optical crystals �?typically one crystals (monocrystalline optical elements) �?which happen to be utilised as gain media for sound-condition lasers. Generally, These are doped with both trivalent exceptional earth ions or transition metallic ions.
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。
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
The host crystal is much more than just a method to fix the laser-Energetic ions at sure positions in Area. Many Houses on the host material are very important:
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。

In 2017, we developed the planet’s largest Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The development of Yb and Tm doped GdScO3 laser crystals with exceptionally huge emission spectra drives the event of laser diode pumped ultrafast sound-condition lasers. With the increase in pulse Power, peak power, and repetition price of solid-state lasers, laser crystals will produce in direction of more substantial sizes, increased crystal excellent, and controllable crucial efficiency.
With that concept, 1 does not want yet another saturable absorber crystal, to make sure that one could make much more compact Q-switched laser click here setups with lessen inner parasitic losses. Having said that, undesired Unwanted side effects can also manifest, for example getting unwanted valence states with the concerned ions or Power transfers.
