Laser modeling and simulation can be utilized to reliably determine the optimum crystal dimensions, doping density And perhaps values of further parameters.

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 changeover cross-sections of pump and laser transitions and likewise the higher-condition life time.

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。

The most feasible doping focus can depend strongly about the host material and its fabrication strategy.

g. a skinny disk. As Yet another case in point, Q-switched lasers achieve an increased population density while in the higher laser level and so are hence a lot more delicate to quenching consequences and Power transfer processes; thus, a reduce doping density is usually suitable for these products. For high-electricity lasers, lower doping densities are frequently utilized to Restrict the density of warmth generation, Though slim-disk lasers get the job done best with very doped crystals. A lot of laser solutions do not reach the complete functionality probable for the reason that such particulars have not been correctly worked out.

Moreover, some flexibility is shed in experiments if one particular can't Check out absorbers with distinct thickness or doping here focus, by way of example, with out 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：

It might be oriented for close to perpendicular incidence in the laser beam, or at Brewster's angle. It could be fastened in a few stable mount which also functions to be a warmth sink. Larger crystals are often used for side pumping e.g. with higher-electrical power diode bars.

Here you'll be able to submit thoughts and reviews. So far as they get acknowledged by the creator, they're going to look over this paragraph along with the writer’s solution. The creator will choose acceptance depending on certain standards. Primarily, the issue has to be of adequately broad desire.

People surfaces that are handed from the laser beam are Commonly either oriented at Brewster's angle or have an anti-reflection coating.

For different explanations, composite crystals have become common. These have a spatially various chemical composition and might be made with Particular designs.

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。

Laser crystals are optical crystals �?usually solitary crystals (monocrystalline optical products) �?which can be applied as gain media for sound-point out lasers. In most cases, They may be doped with both trivalent scarce earth ions or transition metal ions.
