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。

Furthermore, some overall flexibility is shed in experiments if 1 cannot try out absorbers with various thickness or doping concentration, one example is, without exchanging the laser crystal alone.

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 access a higher populace density from the higher laser level and therefore are thus more sensitive to quenching consequences and energy transfer processes; hence, a lower doping density is commonly appropriate for these devices. For high-electrical power lasers, reduced doping densities in many cases are utilized to Restrict the density of heat generation, Even though thin-disk lasers function very best with highly doped crystals. Several laser items tend not to reach the full general performance opportunity due to the fact these types of facts haven't been adequately labored 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。

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。

For quasi-three-amount laser get media or maybe 3-degree acquire media, 1 normally should Restrict the size to a worth which is too short for successful pump absorption, as reabsorption consequences would in any other case spoil the performance. For aspect pumping, supplemental factors appear into Participate in; Apart from productive pump absorption, it can be crucial to obtain a suitable spatial form of your acquire profile.

The medium should have a high transparency (small absorption and scattering) while in the wavelength locations of pump and laser radiation, and excellent optical homogeneity. To some extent, this depends upon here the caliber of the fabric, based on facts of the fabrication system.

Employing our marketing package deal, you can Screen your symbol, additional underneath your product description, and these will been observed by quite a few photonics experts.

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。
