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 elements) �?which happen to be applied as attain media for solid-condition lasers. Usually, These are doped with both trivalent scarce earth ions or changeover steel ions.
Furthermore, some versatility is missing in experiments if a single can not try out absorbers with distinctive thickness or doping concentration, as an example, without having exchanging the laser crystal alone.
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。
Naturally, it is rather appealing that a offered crystal quality is created continuously, Whilst various laser styles may have a distinct sensitivity to content parameters.
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 utilized to reliably determine the ideal crystal dimensions, doping density And maybe values of extra parameters.
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。
For quasi-a few-stage laser obtain media or even 3-level get media, one particular frequently really should limit the duration to a worth that is far too small for productive pump absorption, as reabsorption results would or else spoil the general performance. For side pumping, extra things to consider occur into Perform; Aside from efficient pump absorption, it is crucial to acquire an acceptable spatial shape from the obtain profile.

The medium must have a higher transparency (very low absorption and scattering) inside the wavelength locations of pump and laser radiation, and excellent optical homogeneity. To some extent, this depends on the caliber of the fabric, determined by specifics from the fabrication course of action.
It may be oriented for around perpendicular incidence on the laser beam, or at Brewster's angle. It could be preset in certain stable mount which also functions being a heat sink. Greater get more info crystals are frequently utilized for side pumping e.g. with high-power diode bars.
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。
