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。
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and also the upper-condition life time.
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 skinny disk. As An additional illustration, Q-switched lasers reach a better inhabitants density inside the higher laser amount and are as a result extra delicate to quenching effects and Vitality transfer processes; thus, a lessen doping density is often appropriate for these gadgets. For prime-ability lasers, lower doping densities tend to be used to Restrict the density of heat technology, Whilst slender-disk lasers get the job done finest with remarkably doped crystals. A lot of laser merchandise tend not to reach the comprehensive performance probable due to the fact this kind of details haven't been effectively 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。
