These tables contain only the most typical host crystals; quite a few Other people exist, which can be a lot less often employed.

Moreover, some versatility is missing in experiments if a person are unable to try out absorbers with diverse thickness or doping focus, as an example, without the need of exchanging the laser crystal itself.
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions in addition to the higher-state life time.
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 high surface quality is needless to say critical. Requirements of floor flatness are often much better than . This can help to stop equally scattering losses and wavefront distortions which might degrade the laser's beam excellent. On top of that, scratch and dig technical specs
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 may be used to reliably decide the the best possible crystal Proportions, doping density and possibly values of supplemental parameters.
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。
It is apparent that different purposes produce incredibly unique necessities on laser achieve media. For that reason, a broad variety of various crystals are applied, and generating the correct option is important for developing lasers with ideal overall performance.

The medium must have a large transparency (lower absorption and scattering) from the wavelength locations of pump and laser radiation, and fantastic optical homogeneity. To some extent, this is dependent upon the caliber of the material, determined by information on the fabrication course of action.
It might be oriented for in the vicinity of perpendicular incidence from the laser beam, or at Brewster's angle. It may be fastened in certain solid mount which also acts as a heat sink. More substantial crystals are generally employed for facet pumping e.g. with higher-electrical power diode bars.
