These tables have only the most common host crystals; numerous Other people exist, that are less routinely applied.

In addition, some versatility is shed in experiments if just one can not Check out absorbers with unique thickness or doping focus, such as, without the need 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 superior floor good quality is naturally significant. Technical specs of floor flatness are frequently better than . This will help in order to avoid both of those scattering losses and wavefront distortions which can degrade the laser's beam high quality. Furthermore, scratch and dig requirements
探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。
Laser modeling and simulation can be employed to reliably determine the the best possible crystal Proportions, doping density And maybe values of extra parameters.
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。
It is clear that diverse apps lead to really various necessities on laser acquire media. For that reason, a broad array of different crystals are employed, and generating the proper preference is essential for developing lasers with the best possible effectiveness.

The medium should have a significant transparency (low absorption and scattering) in the wavelength regions of pump and laser radiation, and excellent optical homogeneity. To some extent, this depends upon the quality of the material, based on particulars from the fabrication method.
With That idea, one particular won't need a further saturable absorber crystal, to make sure that just one may possibly make extra compact Q-switched laser setups with lessen inside parasitic losses. Nonetheless, undesirable Negative effects might also occur, which include obtaining unwelcome valence states in the concerned website ions or Electricity transfers.
