These tables comprise only the commonest host crystals; a lot of Other people exist, which can be fewer usually utilised.
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 gives all widespread laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) which has a broad variety of requirements. In addition to the perfectly-established materials, innovative crystals with outstanding Houses like Yb:CALGO can open up new horizons for demanding laser programs. It doesn't matter no matter if personal pieces for R & D needs are necessary or Expense-efficient figures in compact, medium or huge batches with in-time shipping for your output line are required: GWU’s focused service helps to discover the finest Main elements on your software.
Needless to say, it is very desirable that a presented crystal high quality is produced persistently, Even though different laser designs may have another sensitivity to content parameters.
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
The host crystal is considerably more than simply a method to repair the laser-Energetic ions at certain positions in House. A variety of Homes on the host content are crucial:
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。
Individuals surfaces that happen to be handed through the laser beam are Usually possibly oriented at Brewster's angle or have an anti-reflection coating.
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。
The medium should have a significant transparency (lower absorption and scattering) inside the wavelength regions of pump and laser radiation, and excellent optical homogeneity. To some extent, this depends upon get more info the caliber of the fabric, based on facts of your fabrication method.
With That idea, one particular doesn't require a further saturable absorber crystal, making sure that just one could make more compact Q-switched laser setups with lessen inner parasitic losses. Having said that, unwelcome Uncomfortable side effects may additionally happen, for example getting unwelcome valence states from the included ions or energy transfers.
