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。

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。

活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。

g. a thin disk. As One more example, Q-switched lasers attain a greater inhabitants density inside the higher laser level and so are for that reason additional delicate to quenching effects and Vitality transfer procedures; hence, a lower doping density is usually appropriate for these units. For prime-electric power lasers, lessen doping densities in many cases are accustomed to limit the density of warmth generation, Even though slender-disk lasers do the job finest with extremely doped crystals. Quite a few laser items don't reach the total functionality opportunity due to the fact such facts haven't been effectively worked out.

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。

It is obvious that diverse apps produce very various needs on laser obtain media. For that reason, a broad variety of different crystals are utilised, and making the proper option is essential for developing lasers with the best possible general performance.

In 2017, we produced the whole check here world’s greatest Ti∶sapphire crystal (Φ235 mm), which supported The ten 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 strong-condition lasers. With the rise in pulse Power, peak power, and repetition charge of stable-point out lasers, laser crystals will develop in the direction of greater measurements, increased crystal high-quality, and controllable key overall performance.

With that concept, one particular would not need an additional saturable absorber crystal, to ensure that 1 might make much more compact Q-switched laser setups with reduce internal parasitic losses. However, unwelcome side effects may also manifest, for example getting undesirable valence states of the included ions or Vitality transfers.

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。
