These tables consist of only the commonest host crystals; numerous Other individuals exist, that happen to be significantly less routinely utilised.
激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。
Laser crystals are optical crystals �?commonly solitary crystals (monocrystalline optical materials) �?which are applied as get media for sound-state lasers. Most often, These are doped with both trivalent uncommon earth ions or transition metallic ions.
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 transition cross-sections of pump and laser transitions and likewise the higher-state life span.
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。
探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。
Laser modeling and simulation can be used to reliably determine the the best possible crystal dimensions, doping density and possibly values of more parameters.

For quasi-a few-degree laser attain media or perhaps a few-degree achieve media, just one frequently must limit the duration to a value which is way too shorter for productive pump absorption, as reabsorption outcomes would or else spoil the efficiency. For side pumping, extra factors occur into play; Apart from economical pump absorption, it can be crucial to obtain an appropriate spatial shape on the achieve profile.
