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。

A higher surface area quality is not surprisingly vital. Technical specs of surface flatness are frequently better than . This allows to stop equally scattering losses and wavefront distortions which could degrade the laser's beam top quality. Additionally, scratch and dig technical specs

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。

Laser modeling and simulation can be employed to reliably determine the optimum crystal Proportions, doping density and possibly values of extra parameters.

For quasi-three-stage laser attain media or perhaps a few-stage gain media, a single typically should limit the length to a value which can be way too short for effective pump absorption, as reabsorption effects would normally spoil the general performance. For side pumping, extra concerns come into play; In addition to effective pump absorption, it is vital to obtain an appropriate spatial shape of your achieve profile.

Diverse crystalline materials are extremely different regarding their hardness as well as other properties, which ascertain with which approaches And the way easily they may be Reduce and polished with good quality.

For many factors, composite crystals have become well known. These have a spatially various chemical composition and might be made with Particular designs.

There is certainly a wide array of crystalline media, which can be grouped according to special atomic constituents and crystalline buildings. Some crucial teams of crystals are:

激光晶体（laser check here 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。
