The most typical laser-active unusual earth ions and host media along with some standard emission wavelengths are proven in the next table:
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。
为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。
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。
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 offers all frequent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etc.) using a broad selection of requirements. In addition to the effectively-established supplies, modern crystals with exceptional Homes like Yb:CALGO can open new horizons for demanding laser purposes. It doesn't matter regardless of whether personal items for R & D uses are needed or cost-successful figures in compact, medium or significant batches with in-time shipping and delivery to the manufacturing line are required: GWU’s focused provider helps to discover the very best Main parts for your software.
Naturally, it is vitally attractive that a specified crystal quality is created regularly, although various laser styles can have a special sensitivity to materials parameters.
g. a skinny disk. As Yet another case in point, Q-switched lasers get to a higher populace density within the upper laser degree and they are thus much more delicate to quenching effects and Electricity transfer processes; thus, a decreased doping density is commonly appropriate for these gadgets. For prime-electric power lasers, lower doping densities are sometimes accustomed to limit the density of warmth technology, Even though thin-disk lasers perform greatest with highly doped crystals. Quite a few laser merchandise do not reach the whole overall performance potential mainly because this kind of details have not been thoroughly worked out.
The host crystal is a lot more than simply a method to repair the laser-Lively ions at particular positions in space. Several Houses in the host materials 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。

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 in excess of thirty many years of expertise in distributing laser crystals. Pick GWU to get pleasure from our extensive expertise and in-field experience!
With website that concept, just one does not want a further saturable absorber crystal, so that just one may make additional compact Q-switched laser setups with decrease interior parasitic losses. On the other hand, undesired Uncomfortable side effects could also manifest, which include acquiring unwanted valence states from the associated ions or Strength transfers.
