为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。
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。
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 A further instance, Q-switched lasers arrive at a greater populace density in the upper laser stage and they are as a result additional delicate to quenching consequences and Power transfer processes; for that reason, a decreased doping density is commonly suitable for these equipment. For top-power lasers, decreased doping densities will often be utilized to limit the density of warmth generation, Though skinny-disk lasers function best with highly doped crystals. A lot of laser solutions usually do not get to the whole overall performance potential due to the fact this sort of information haven't been properly worked out.
The host crystal is much more than just a method to fix the laser-Energetic ions at certain positions in click here House. A number of Qualities with the host materials are important:
热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。
All those surfaces which might be passed by the laser beam are Commonly either oriented at Brewster's angle or have an anti-reflection coating.

In 2017, we made the globe’s most significant 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 development of laser diode pumped ultrafast strong-point out lasers. With the increase in pulse Strength, peak energy, and repetition charge of stable-condition lasers, laser crystals will build in the direction of bigger dimensions, bigger crystal quality, and controllable key efficiency.
It could be oriented for around perpendicular incidence of your laser beam, or at Brewster's angle. It can be fixed in some strong mount which also functions to be a heat sink. Greater crystals usually are employed for aspect pumping e.g. with large-electrical power diode bars.
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。
