The commonest laser-Energetic scarce earth ions and host media along with some regular emission wavelengths are proven in the following desk:

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 �?ordinarily solitary crystals (monocrystalline optical materials) �?which happen to be utilised as gain media for reliable-point out lasers. Generally, These are doped with either trivalent unusual earth ions or changeover steel ions.

激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。

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 significant surface top quality is certainly essential. Specs of surface area flatness in many cases are much better than . This helps to prevent the two scattering losses and wavefront distortions which could degrade the laser's beam high-quality. In addition, scratch and dig technical specs

The utmost probable doping concentration can count strongly to the host materials and its fabrication system.

A few laser crystal elements happen to be shown where by some saturable absorber content is included for passive Q switching of the laser.

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-degree laser gain media or simply 3-amount achieve media, a single often should limit the size to a worth which can be as well shorter for effective pump absorption, as more info reabsorption consequences would normally spoil the performance. For aspect pumping, supplemental factors appear into Participate in; In addition to productive pump absorption, it is important to obtain a suitable spatial shape in the get profile.

主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。

The medium ought to have a substantial transparency (reduced absorption and scattering) in the wavelength areas of pump and laser radiation, and great optical homogeneity. To some extent, this depends on the caliber of the fabric, determined by aspects in the fabrication system.

It might be oriented for around perpendicular incidence on the laser beam, or at Brewster's angle. It might be fixed in certain solid mount which also functions to be a warmth sink. Much larger crystals tend to be useful for aspect pumping e.g. with large-electrical 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。
