These tables include only the most typical host crystals; a lot of Other people exist, which happen to be much less commonly made use of.
These ions allow the crystal to amplify mild at the laser wavelength by using stimulated emission, when Electrical power is provided to 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 transition cross-sections of pump and laser transitions in addition to the upper-condition life span.

A significant surface area quality is naturally important. Specs of surface flatness are sometimes much better than . This assists in order to avoid both equally scattering losses and wavefront distortions which can degrade the laser's beam high quality. Furthermore, scratch and dig specs
g. a skinny disk. As An additional illustration, Q-switched lasers arrive at a higher populace density in the upper laser degree and so are therefore far more delicate to quenching effects and Strength transfer procedures; therefore, a reduced doping density is frequently suitable for these units. For prime-electricity lasers, decreased doping densities are often used to Restrict the density of warmth era, although thin-disk lasers work best with highly doped crystals. Lots of laser products and solutions never get to the total efficiency possible mainly because these types of facts have not been properly worked out.
The host crystal is much more than just a method to fix the laser-Energetic ions at certain positions in Room. Many Qualities in the host material are essential:
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 programs cause incredibly unique prerequisites on laser attain media. Due to this, a wide vary of various crystals are utilised, and producing the correct selection is essential for developing lasers with ideal overall more info performance.
Distinctive crystalline resources are extremely unique concerning their hardness and various Qualities, which ascertain with which techniques and how very easily they may be Slash and polished with good quality.
GWU-Lasertechnik has over 30 several years of encounter in distributing laser crystals. Select GWU to take advantage of our vast know-how As well as in-discipline practical experience!
There exists a wide range of crystalline media, that may be grouped in accordance to big atomic constituents and crystalline buildings. Some significant teams of crystals are:
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。
