These tables comprise only the commonest host crystals; lots of Other people exist, that are a lot less often 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。
芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。
Also, some overall flexibility is misplaced in experiments if 1 are unable to Check out absorbers with distinct thickness or doping concentration, by way of example, devoid of exchanging the laser crystal by itself.
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：
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
A large area good quality is obviously critical. Requirements of surface flatness in many cases are better than . This can help to prevent both of those scattering losses and wavefront distortions which might degrade the laser's beam quality. Moreover, scratch and dig specifications
The most feasible doping concentration can rely strongly over the host product and its fabrication method.
A couple of laser crystal materials are actually demonstrated exactly where some saturable absorber product is integrated for passive Q switching of a laser.
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。

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 different causes, composite crystals have become well-known. These Have got a spatially various chemical composition and can be produced with special designs.
With That idea, one isn't going to want a further saturable absorber crystal, to make sure that 1 may make much more compact Q-switched laser setups with decreased interior parasitic losses. Nevertheless, unwelcome Unwanted side effects may take place, like acquiring unwelcome valence states of your involved ions or Vitality transfers.
