In addition, some versatility is dropped in experiments if just one are unable to Check out absorbers with various thickness or doping concentration, by way of example, with out exchanging the laser crystal 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 substantial floor high-quality is obviously crucial. Specifications of surface flatness are frequently a lot better than . This will help in order to avoid equally scattering losses and wavefront distortions which often can degrade the laser's beam excellent. Also, 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 possibly values of supplemental parameters.

Those people surfaces which are passed via the laser beam are normally both 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 ought to have a high transparency (lower absorption and scattering) inside the wavelength locations of pump and laser radiation, and excellent optical homogeneity. To some extent, this depends upon the standard of the material, determined by aspects in the fabrication process.
Applying our marketing offer, you could Exhibit your emblem, further more down below your product description, and these will been witnessed by numerous photonics pros.
