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。

Which geometry, dopant and doping focus of the get medium are most advantageous rely upon numerous components. The available pump resource (sort of laser diode or lamp) as well as the envisaged pumping arrangement are important variables, but the material alone also has some impact. Such as, titanium–sapphire lasers need to be pumped with high intensities, for which the form of the transversely cooled rod, operated with fairly little pump and laser beam diameter, is much more ideal than e.
晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。
A significant area high-quality is of course crucial. Specs of floor flatness in many cases are a lot better than . This will help to stay away from equally scattering losses and wavefront distortions which may degrade the laser's beam excellent. Additionally, scratch and dig specifications
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。
The host crystal is a lot more than just a way to fix the laser-Lively ions at particular positions in Place. Numerous Houses from the host content are very important:
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。

Unique crystalline resources are quite different concerning their hardness and also other Qualities, which figure out with more info which methods and how simply they are often Lower and polished with good quality.
The medium should have a large transparency (low absorption and scattering) inside the wavelength regions of pump and laser radiation, and excellent optical homogeneity. To some extent, this depends upon the standard of the material, based on aspects in the fabrication system.
