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。
This is simple to do: just find the lock icon in front of the URL while in the tackle bar and drag that for the bookmark toolbar Along with the mouse. In case you discover the bookmark entry much too long, you could ideal-click it to edit the text, e.g. working with "RP Enc" instead of "RP Photonics Encyclopedia".
GWU offers all common laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so on.) using a broad number of specifications. Aside from the properly-proven resources, modern crystals with exceptional Qualities like Yb:CALGO can open up new horizons for demanding laser apps. No matter whether or not individual items for R & D functions are demanded or Value-effective quantities in little, medium or big batches with in-time shipping for your generation line are required: GWU’s committed service helps to discover the most effective core elements in your software.
A large floor good quality is certainly essential. Specs of area flatness tend to be better than . This aids to stop both equally scattering losses and wavefront distortions which often can degrade the laser's beam high-quality. In addition, scratch and dig specifications
The utmost probable doping concentration can count strongly around the host materials and its fabrication method.
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。
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。
It is clear that different purposes bring about quite diverse necessities on laser get media. Due to this, a wide selection of different crystals are utilized, and creating the proper choice is important for setting up lasers with optimum general performance.

In 2017, we made the globe’s largest Ti∶sapphire crystal (Φ235 mm), check here which supported the 10 PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with exceptionally vast emission spectra drives the development of laser diode pumped ultrafast stable-point out lasers. With the increase in pulse Vitality, peak electricity, and repetition level of solid-state lasers, laser crystals will create in direction of much larger dimensions, better crystal high-quality, and controllable key overall performance.
There is certainly a wide array of crystalline media, which may be grouped in accordance to big atomic constituents and crystalline buildings. Some important teams of crystals are:
