The most typical laser-Energetic scarce earth ions and host media together with some typical emission wavelengths are demonstrated in the following table:
These ions empower the crystal to amplify mild in the laser wavelength through stimulated emission, when Power is equipped into the crystal by means of absorption of pump light-weight (�?optical pumping
Laser crystals are optical crystals �?typically solitary crystals (monocrystalline optical elements) �?that happen to be utilised as acquire media for stable-state lasers. Usually, they are doped with either trivalent unusual earth ions or changeover 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。
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：
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。
The maximum probable doping focus can depend strongly about the host product and its fabrication system.
Laser modeling and simulation may be used to reliably ascertain the ideal crystal Proportions, click here doping density And maybe values of additional parameters.
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。
It is obvious that distinctive apps cause incredibly unique necessities on laser gain media. For that reason, a broad array of various crystals are utilised, and building the correct preference is important for developing lasers with optimum functionality.
