These tables have only the most typical host crystals; quite a few Other individuals exist, which happen to be fewer commonly applied.
激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。

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：
GWU features all popular laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etc.) with a broad number of specifications. In addition to the effectively-proven resources, modern crystals with fantastic Homes like Yb:CALGO can open new horizons for demanding laser programs. Regardless of no matter whether specific pieces for R & D functions are required or Price tag-economical numbers in little, medium or massive batches with in-time shipping for your manufacturing line are essential: GWU’s focused service helps you to locate the very best Main elements for the software.
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
g. a thin disk. As A different case in point, Q-switched lasers reach a greater populace density while in the higher laser stage and are thus extra delicate to quenching consequences and energy transfer processes; consequently, a reduced doping density get more info is usually appropriate for these units. For prime-energy lasers, reduce doping densities are frequently used to Restrict the density of heat generation, Even though thin-disk lasers work best with really doped crystals. Quite a few laser solutions tend not to reach the full performance probable mainly because these kinds of facts have not been thoroughly labored out.
A handful of laser crystal supplies are demonstrated where by some saturable absorber product is integrated for passive Q switching of the laser.
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。

For a variety of factors, composite crystals are getting to be popular. These Have a very spatially varying chemical composition and can be designed with special shapes.
With that concept, 1 doesn't have to have an additional saturable absorber crystal, to ensure 1 may well make a lot more compact Q-switched laser setups with decrease interior parasitic losses. Even so, undesirable Unwanted side effects might also come about, including acquiring unwanted valence states on the involved ions or Strength transfers.
