The commonest laser-Energetic exceptional earth ions and host media along with some normal emission wavelengths are proven in the following desk:
These ions permit the crystal to amplify light within the laser wavelength by means of stimulated emission, when Vitality is supplied towards the crystal by way of absorption of pump light-weight (�?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 and in addition the higher-condition life span.

A significant area high quality is naturally vital. Specifications of surface flatness are sometimes a lot better than . This can help in order to avoid both equally scattering losses and wavefront distortions that may degrade the laser's beam quality. Furthermore, scratch and dig specs
The maximum possible doping concentration can count strongly on the host substance and its fabrication system.
The host crystal is considerably more than simply a method to fix the laser-Lively ions at certain positions in Room. A variety of properties in the host content are very important:
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 apparent that distinct purposes bring about very distinctive necessities on laser attain media. For this reason, a wide variety of various crystals are used, and making the best selection get more info is essential for setting up lasers with the best possible general performance.
Distinct crystalline materials are quite distinct regarding their hardness as well as other Attributes, which decide with which strategies And exactly how very easily they may be Reduce and polished with high quality.
For several good reasons, composite crystals have gotten common. These Possess a spatially varying chemical composition and will be manufactured with Particular shapes.
There is an array of crystalline media, which may be grouped in accordance to big atomic constituents and crystalline buildings. Some essential groups of crystals are:
