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 �?generally single crystals (monocrystalline optical resources) �?that are applied as acquire media for stable-point out lasers. Normally, they are doped with both trivalent scarce earth ions or transition steel ions.

Moreover, some adaptability is shed in experiments if 1 are not able to try out absorbers with diverse thickness or doping focus, one example is, without 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：

A higher floor high-quality is of course important. Specifications of surface flatness are often much better than . This will help to stop equally scattering losses and wavefront distortions which may degrade the laser's beam high quality. Additionally, scratch and dig technical specs

g. a skinny disk. As another example, Q-switched lasers achieve an increased inhabitants density in the upper laser degree and so are hence more delicate to quenching consequences and energy transfer processes; therefore, a lower doping density is often appropriate for these equipment. For more info top-electric power lasers, reduced doping densities will often be utilized to Restrict the density of heat generation, although slender-disk lasers operate greatest with extremely doped crystals. Lots of laser solutions don't reach the full general performance probable since such information haven't been appropriately labored out.

The host crystal is a great deal more than simply a method to repair the laser-Lively ions at sure positions in space. Numerous Qualities in the host content are very important:

It is obvious that distinctive purposes lead to very various specifications on laser acquire media. Because of this, a broad range of various crystals are utilised, and generating the best selection is essential for developing lasers with the best possible effectiveness.

The medium must have a large transparency (low absorption and scattering) from the wavelength regions of pump and laser radiation, and superior optical homogeneity. To some extent, this relies on the caliber of the fabric, determined by information of the fabrication method.

With that concept, 1 doesn't require a further saturable absorber crystal, making sure that just one may possibly make a lot more compact Q-switched laser setups with reduced internal parasitic losses. Having said that, undesired Unwanted effects can also occur, for instance obtaining undesired valence states from the included ions or Vitality transfers.

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。
