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。

Also, some flexibility is misplaced in experiments if 1 are not able to Check out absorbers with various thickness or doping focus, one example is, without the need of exchanging the laser crystal by itself.

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 example, Q-switched lasers access a higher populace density in the upper laser level and therefore are hence a lot more delicate to quenching consequences and Power transfer procedures; therefore, a decrease doping density is commonly suitable for these devices. For high-electrical power lasers, decreased doping densities are often used to Restrict the density read more of heat generation, Though skinny-disk lasers perform greatest with extremely doped crystals. Numerous laser goods do not reach the full overall performance potential for the reason that these types of information have not been thoroughly 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。

It is obvious that different programs cause pretty different requirements on laser gain media. For that reason, a broad range of various crystals are utilised, and producing the proper preference is essential for constructing lasers with ideal efficiency.

For many explanations, composite crystals have gotten well-known. These have a spatially different chemical composition and may be built with Specific shapes.

It may be oriented for around perpendicular incidence on the laser beam, or at Brewster's angle. It could be fastened in some sound mount which also acts like a heat sink. Bigger crystals are generally utilized for side pumping e.g. with higher-energy 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。
