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。
On top of that, some adaptability is lost in experiments if one can't try out absorbers with unique thickness or doping focus, one example is, 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。
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。
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
A couple of laser crystal resources have been demonstrated in which some saturable absorber material is incorporated for passive Q switching of a laser.

It is clear that distinctive apps bring on pretty distinctive prerequisites on laser get media. This is why, a broad variety of various crystals are utilised, and producing the right preference is essential for developing lasers with ideal overall performance.

The medium must have a high transparency (lower absorption and scattering) within the wavelength areas of pump and laser radiation, and good optical homogeneity. To some extent, this is dependent upon the standard of the material, based on details on the fabrication procedure.
With That idea, one does not have to have yet another saturable absorber crystal, to make sure that just one may possibly make a lot more compact Q-switched laser setups with reduce interior parasitic losses. On the other hand, undesirable Negative effects can also occur, for instance obtaining undesired valence states from the included ions or Power click here transfers.
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。
