The commonest laser-active rare earth ions and host media along with some standard emission wavelengths are demonstrated in the subsequent table:
These ions empower the crystal to amplify gentle for the laser wavelength by means of stimulated emission, when Electricity is equipped to your crystal by means of absorption of pump gentle (�?optical pumping
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。
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：

A higher surface quality is of course important. Specs of surface area flatness in many cases are better than . This assists to prevent equally scattering losses and wavefront distortions that may degrade the laser's beam high quality. Moreover, scratch and dig specifications
The utmost probable doping focus can count strongly about the host materials and its fabrication approach.
Laser modeling and simulation can be used to reliably determine the optimum crystal dimensions, doping density and possibly values of added 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 programs result in extremely different demands on laser attain media. Due to this, a broad assortment of different crystals are made use of, and creating the proper decision is important for setting up lasers with optimum overall performance.

For many motives, composite crystals are becoming well-known. These Use a spatially different chemical composition and can be made with Unique designs.
There is certainly a wide range of crystalline website media, which may be grouped according to important atomic constituents and crystalline buildings. Some vital groups of crystals are:
