These tables incorporate only the commonest host crystals; several Other folks exist, which are less frequently utilized.
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 �?usually solitary crystals (monocrystalline optical supplies) �?that happen to be applied as achieve media for solid-point out lasers. In most cases, they are doped with either trivalent rare earth ions or changeover metallic ions.
Moreover, some overall flexibility is shed in experiments if one particular are not able to try out absorbers with different thickness or doping focus, one example is, devoid of exchanging the laser crystal itself.
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:

Obviously, it's very appealing that a specified crystal quality is created continuously, Though distinctive laser models might have another sensitivity to content parameters.
The utmost probable doping concentration can depend strongly about the host substance and its fabrication technique.
The host crystal is far more than simply a way to repair the laser-active ions at certain positions in House. Quite a few properties with the host product are important:
蓝宝�?柱面�?球罩 偏振�?棱镜 红外光学元件 反射�?光学窗口 非球面镜 波片 分光�?制造能力
For quasi-three-level laser attain media or even 3-degree obtain media, 1 frequently needs to Restrict the length to a worth which can be as well shorter for productive pump absorption, as reabsorption effects would usually spoil the efficiency. For facet pumping, further considerations arrive into Enjoy; In addition to economical pump absorption, it is vital to get an acceptable spatial condition from the get profile.

The medium must have a substantial transparency (small absorption and scattering) while in the wavelength locations of pump and laser radiation, and fantastic optical homogeneity. To some extent, this is determined by the quality of the material, based on information website on the fabrication system.
It might be oriented for in the vicinity of perpendicular incidence of the laser beam, or at Brewster's angle. It can be mounted in a few stable mount which also functions for a heat sink. Much larger crystals tend to be used for facet pumping e.g. with superior-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。
