激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。

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 appealing that a offered crystal high quality is produced consistently, Whilst different laser styles might have a unique sensitivity to materials parameters.

g. a skinny disk. As An additional case in point, Q-switched lasers attain an increased inhabitants density inside the higher laser amount and they are consequently far more delicate to quenching outcomes and Power transfer procedures; consequently, a reduce doping density is often appropriate for these units. For prime-electrical power lasers, reduce doping densities are frequently utilized to limit the density of heat era, Despite the fact that slender-disk lasers function most effective with remarkably doped crystals. Numerous laser solutions tend not to reach the full effectiveness prospective for the reason that such specifics haven't been correctly worked out.

The host crystal is way check here more than just a means to fix the laser-active ions at particular positions in Place. A number of properties from the host content are essential:

量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。

All those surfaces which might be passed by the laser beam are Commonly 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 created the earth’s biggest Ti∶sapphire crystal (Φ235 mm), which supported the 10 PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with very huge emission spectra drives the event of laser diode pumped ultrafast sound-condition lasers. With the rise in pulse energy, peak electricity, and repetition amount of strong-condition lasers, laser crystals will produce to larger sizes, greater crystal good quality, and controllable essential effectiveness.

There's an array of crystalline media, which may be grouped in accordance to special atomic constituents and crystalline buildings. Some vital 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。
