The most common laser-Lively exceptional earth ions and host media together with some common emission wavelengths are revealed in the next desk:
These ions help the crystal to amplify gentle in the laser wavelength via stimulated emission, when Electricity is provided to your crystal by means of absorption of pump mild (�?optical pumping
Laser crystals are optical crystals �?normally solitary crystals (monocrystalline optical supplies) �?which happen to be made use of as gain media for sound-state lasers. In most cases, These are doped with either trivalent rare earth ions or transition metal ions.

A higher surface area good quality is naturally essential. Technical specs of surface area flatness are often a lot better than . This assists to stay away from equally scattering losses and wavefront distortions which could degrade the laser's beam quality. Also, scratch and dig specifications
The maximum feasible doping concentration can depend strongly around the host content and its fabrication system.
激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。
热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。
It is obvious that various programs produce extremely diverse necessities on laser gain media. This is why, a broad assortment of different crystals are applied, and building the correct alternative is important for setting up lasers with the best possible effectiveness.
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。
GWU-Lasertechnik has much more than thirty a long time of experience in distributing laser website crystals. Pick GWU to gain from our large expertise and in-area experience!
You can find an array of crystalline media, that may be grouped according to special atomic constituents and crystalline buildings. Some critical groups of crystals are:
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。
