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。
Additionally, some versatility is dropped in experiments if one particular are not able to try out absorbers with distinct thickness or doping focus, such as, without the need of 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。
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
g. a thin disk. As A different example, Q-switched lasers get to the next population density while in the higher laser level and therefore are thus more sensitive to quenching results and Electricity transfer procedures; hence, a lessen doping density is often appropriate for these gadgets. For prime-electricity lasers, decreased doping densities in many cases are utilized to Restrict the density of heat era, Though skinny-disk lasers perform greatest with very doped crystals. Lots of laser items usually do not reach the total efficiency prospective simply because such aspects 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。
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 achieve media and even a few-amount achieve media, a single often ought to limit the size to a worth that's too brief for economical pump absorption, as reabsorption results would if not spoil the efficiency. For facet pumping, additional issues occur into play; Aside from productive pump absorption, it can be crucial to obtain a suitable spatial form on the acquire profile.

There's an array of crystalline media, which may be grouped according to special atomic constituents and crystalline constructions. Some critical click here teams of crystals are:
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。
