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：
GWU gives all common laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) that has a broad variety of specs. Moreover the nicely-proven products, revolutionary crystals with fantastic Qualities like Yb:CALGO can open new horizons for demanding laser purposes. Despite regardless of whether individual pieces for R & D uses are needed or Charge-efficient numbers in modest, medium or significant batches with in-time delivery to the generation line are essential: GWU’s committed company helps to find the very best core elements on your software.
A significant area quality is of course vital. Specifications of surface flatness tend to be better than . This will help to stop both equally scattering losses and wavefront distortions which often can degrade the laser's beam high-quality. Also, scratch and dig requirements
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 few laser crystal resources are actually demonstrated the place some saturable absorber product is incorporated for passive Q switching of the laser.
蓝宝�?柱面�?球罩 偏振�?棱镜 红外光学元件 反射�?光学窗口 非球面镜 波片 分光�?制造能力
Those surfaces which are handed from the laser beam are Ordinarily both oriented at Brewster's angle or have an anti-reflection coating.

In 2017, we made the globe’s premier click here 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 really wide emission spectra drives the development of laser diode pumped ultrafast reliable-point out lasers. With the increase in pulse Strength, peak electric power, and repetition fee of stable-condition lasers, laser crystals will establish towards bigger sizes, larger crystal good quality, and controllable essential effectiveness.
There's an array of crystalline media, which may be grouped in accordance to big atomic constituents and crystalline buildings. Some critical 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。
