These tables include only the most typical host crystals; many Other folks exist, that are a lot less frequently employed.
These ions enable the crystal to amplify light-weight with the laser wavelength by way of stimulated emission, when energy is provided towards the crystal by using absorption of pump gentle (�?optical pumping
激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。
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。
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions in addition to the upper-state life time.

A substantial area high quality is naturally vital. Specifications of surface flatness are sometimes a lot better than . This allows to prevent the two scattering losses and wavefront distortions which could degrade the laser's beam excellent. Also, scratch and dig requirements
g. a thin disk. As A different example, Q-switched lasers get to the next populace density in the upper laser degree and so are hence much more sensitive to quenching outcomes and Electricity transfer processes; consequently, a reduced doping density is frequently suitable for these products. For prime-electric power lasers, lessen doping densities tend to be used to limit the density of heat technology, although slender-disk lasers do the job most effective with remarkably doped crystals. Quite a few laser products don't get to the whole effectiveness likely since this kind of details haven't been correctly Laser Crystal labored out.
The host crystal is far more than just a way to repair the laser-Lively ions at particular positions in Room. Many properties in the host content are crucial:
量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。
People surfaces which might be passed by the laser beam are Commonly either oriented at Brewster's angle or have an anti-reflection coating.

The medium should have a superior transparency (small absorption and scattering) from the wavelength regions of pump and laser radiation, and superior optical homogeneity. To some extent, this is determined by the quality of the fabric, based on specifics of your fabrication approach.
There's a variety of crystalline media, which may be grouped according to special atomic constituents and crystalline constructions. Some essential groups of crystals are:
