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。

The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and in addition the upper-condition life time.
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
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 skinny disk. As Yet another illustration, Q-switched lasers get to a higher populace density during the upper laser stage and they are consequently far more delicate to quenching consequences and energy transfer processes; consequently, a reduced doping density is usually appropriate for these units. For prime-electric power lasers, reduced doping densities are frequently accustomed to limit the density of heat generation, Though skinny-disk lasers perform greatest with click here very doped crystals. Numerous laser goods don't get to the entire functionality prospective since such facts have not been adequately worked out.
Laser modeling and simulation can be used to reliably decide the the best possible crystal dimensions, doping density and possibly values of more parameters.
