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（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。
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 features all prevalent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so forth.) by using a broad range of specifications. Besides the perfectly-founded resources, impressive crystals with fantastic Homes like Yb:CALGO can open up new horizons for demanding laser apps. Despite no matter if particular person items for R & D applications are required or Charge-efficient figures in compact, medium or significant batches with in-time delivery for the production line are needed: GWU’s focused assistance helps to discover the most effective Main components on your application.
A superior floor high-quality is naturally critical. Requirements of area flatness tend to be better than . This allows to avoid both equally scattering losses and wavefront distortions which may degrade the laser's beam high-quality. Furthermore, scratch and dig technical specs
探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。
Laser modeling and simulation can be utilized to reliably decide the optimum crystal dimensions, doping density and possibly values of additional parameters.
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。
It is clear that diverse programs produce incredibly diverse specifications on laser obtain media. Due more info to this, a broad vary of various crystals are used, and generating the best option is essential for developing lasers with the best possible overall performance.
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 designed the earth’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 really extensive emission spectra drives the development of laser diode pumped ultrafast strong-point out lasers. With the rise in pulse energy, peak power, and repetition price of solid-condition lasers, laser crystals will establish to more substantial sizes, higher crystal quality, and controllable key effectiveness.
It could be oriented for in close proximity to perpendicular incidence of your laser beam, or at Brewster's angle. It might be fastened in a few stable mount which also functions for a heat sink. Much larger crystals are usually employed for aspect pumping e.g. with substantial-energy diode bars.
