Different crystalline components are extremely various concerning their hardness and other properties, which decide with which strategies And the way easily they can be Slash and polished with high quality.
人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and likewise the upper-point out life span.
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
For quasi-three-degree laser gain media and even three-degree acquire media, one particular typically must Restrict the size to a worth which can be much too small for effective pump absorption, as reabsorption results would normally spoil the general performance. For side pumping, supplemental factors appear into play; Moreover efficient pump absorption, it is vital to get an appropriate spatial form in the attain profile.
g. a thin disk. As One more case in point, Q-switched lasers reach a greater populace density within the upper laser degree and they are hence far more delicate to quenching results and Electricity transfer processes; therefore, a decreased doping density is frequently suitable for these devices. For prime-electrical power lasers, lower doping densities are frequently accustomed to Restrict the density of heat generation, although slender-disk lasers function greatest with highly doped crystals. Quite a few laser items do not reach the comprehensive functionality potential due to the fact such specifics haven't been thoroughly labored out.

A higher hurt threshold when it comes to pulse fluence or peak intensity is often important for high-Strength amplifiers.
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：

It might be oriented for near perpendicular incidence from the laser beam, or at Brewster's angle. It check here could be fixed in a few good mount which also acts being a warmth sink. Bigger crystals usually are used for side pumping e.g. with large-ability diode bars.
The most common laser-active rare earth ions and host media together with some typical emission wavelengths are revealed in the subsequent desk:
Individuals surfaces which happen to be passed because of the laser beam are Usually both oriented at Brewster's angle or have an anti-reflection coating.
Of course, it is very attractive that a specified crystal high-quality is generated continually, Despite the fact that distinct laser styles might have a distinct sensitivity to materials parameters.
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。
With that concept, a person isn't going to need an extra saturable absorber crystal, so that a single may perhaps make much more compact Q-switched laser setups with decreased interior parasitic losses. Nonetheless, undesired Unwanted side effects may additionally manifest, such as obtaining unwanted valence states from the concerned ions or Strength transfers.

Laser crystals are optical crystals �?generally solitary crystals (monocrystalline optical resources) �?which happen to be utilized as acquire media for solid-state lasers. Most often, They can be doped with either trivalent scarce earth ions or transition metallic ions.
