The most common laser-active uncommon earth ions and host media together with some common emission wavelengths are shown in the subsequent table:
These ions allow the crystal to amplify light for the laser wavelength through stimulated emission, when Power is equipped on the crystal by way of absorption of pump light-weight (�?optical pumping
芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。
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 upper-condition life span.

For quasi-three-amount laser get media and even three-stage get media, one particular frequently really should limit the duration to a price that is far too quick for economical pump absorption, as reabsorption results would usually spoil the efficiency. For side pumping, further considerations occur into Perform; Moreover productive pump absorption, it's important to get an acceptable spatial form of your achieve profile.
