Laser crystals are optical crystals �?normally solitary crystals (monocrystalline optical materials) �?which happen to be utilised as acquire media for stable-state lasers. Most often, They may be doped with possibly trivalent exceptional earth ions or transition steel ions.

激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。

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。

Obviously, it is very desirable that a given crystal high quality is generated regularly, While distinctive laser patterns might have a unique sensitivity to content parameters.

The utmost doable doping concentration can count strongly over the host content and its fabrication process.

激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。

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。

For quasi-3-amount laser achieve media and even a few-degree get media, a single normally has to Restrict the duration to a value that is way too shorter for efficient pump absorption, as reabsorption effects would usually spoil the overall performance. For aspect pumping, supplemental factors appear into Engage in; Other than effective pump absorption, it is important to obtain an acceptable spatial shape from the acquire profile.

In 2017, check here we made the entire world’s most significant 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 incredibly huge emission spectra drives the event of laser diode pumped ultrafast reliable-point out lasers. With the rise in pulse energy, peak electrical power, and repetition amount of good-point out lasers, laser crystals will develop in the direction of greater measurements, increased crystal excellent, and controllable critical efficiency.

There is a variety of crystalline media, that may be grouped in accordance to important atomic constituents and crystalline constructions. Some vital groups 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。
