These tables include only the most typical host crystals; a lot of Other people exist, which can be less routinely utilized.

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。

Which geometry, dopant and doping focus of the attain medium are most useful depend on numerous factors. The obtainable pump resource (sort of laser diode or lamp) and also the envisaged pumping arrangement are essential components, but the fabric by itself also has some affect. For instance, titanium–sapphire lasers have to be pumped with large intensities, for which the form of a transversely cooled rod, operated with fairly tiny pump and laser beam diameter, is more proper than e.

GWU offers all widespread laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so on.) that has a broad variety of technical specs. Aside from the very well-recognized supplies, ground breaking crystals with exceptional Homes like Yb:CALGO can open up new horizons for demanding laser applications. It doesn't matter regardless of whether individual pieces for R & D purposes are demanded or Expense-successful figures in compact, medium or huge batches with in-time shipping and delivery for that production line are wanted: GWU’s committed support helps you to discover the greatest core factors for your personal application.

A high area high-quality is of course here crucial. Requirements of floor flatness are often better than . This will help to stop both of those scattering losses and wavefront distortions which can degrade the laser's beam high-quality. Also, scratch and dig technical specs

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。

激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。

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 quasi-3-stage laser get media or maybe 3-degree acquire media, a single frequently must limit the duration to a value which is far too quick for effective pump absorption, as reabsorption outcomes would normally spoil the performance. For facet pumping, further considerations appear into play; Aside from efficient pump absorption, it is crucial to acquire a suitable spatial form of your gain profile.

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。

For many reasons, composite crystals are becoming well-liked. These Possess a spatially varying chemical composition and can be produced with Unique shapes.

There exists a variety of crystalline media, which can be grouped according to special atomic constituents and crystalline buildings. Some important groups 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。
