These tables include only the most common host crystals; quite a few Some others exist, which happen to be considerably less routinely employed.
激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。
Laser crystals are optical crystals �?normally solitary crystals (monocrystalline optical elements) �?which might be applied as obtain media for stable-state lasers. Normally, These are doped with both trivalent scarce earth ions or changeover metallic ions.
On top of that, some flexibility is dropped in experiments if a person are not able to Check out absorbers with unique thickness or doping focus, as an example, with out exchanging the laser crystal by itself.
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。
A handful of laser crystal resources are demonstrated wherever some saturable absorber materials is integrated for passive Q switching of a laser.
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。
People surfaces which are passed through the laser beam are Typically both oriented at Brewster's angle or have an anti-reflection coating.
主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。
In 2017, we designed the world’s greatest Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event read more of Yb and Tm doped GdScO3 laser crystals with extremely large emission spectra drives the event of laser diode pumped ultrafast strong-point out lasers. With the increase in pulse energy, peak power, and repetition rate of reliable-condition lasers, laser crystals will build to larger sized sizes, larger crystal high quality, and controllable critical general performance.
There is a wide array of crystalline media, which can be grouped according to important atomic constituents and crystalline constructions. Some crucial teams of crystals are:
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。
