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。
激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and in addition the higher-condition life span.
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 excellent is certainly crucial. Specs of surface area flatness will often be much better than . This helps to avoid both of those scattering losses and wavefront distortions which might degrade the laser's beam high-quality. Moreover, scratch and dig specs
g. a thin disk. As A further example, Q-switched lasers get to a better inhabitants density in the upper laser level and are thus more delicate to quenching effects and Power transfer processes; as a result, a decrease doping density is usually appropriate for these equipment. For top-energy lasers, reduced doping densities are often used to Restrict the density of heat technology, Whilst slim-disk lasers operate greatest with extremely doped crystals. Numerous laser products usually do not reach the total general performance opportunity simply because these specifics have not been adequately labored out.
激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。
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。
All those surfaces which are passed because of the laser beam are Typically possibly oriented at Brewster's angle or have an anti-reflection coating.

The medium must have a higher transparency (reduced absorption and scattering) from the wavelength locations of pump and laser radiation, and good optical homogeneity. To some extent, this depends on the quality of the material, determined by facts from the fabrication approach.
It could be oriented for close to perpendicular incidence from the laser beam, or at Brewster's angle. It may be preset in a few sound mount which also acts being a click here heat sink. Much larger crystals are usually employed for aspect pumping e.g. with higher-electrical power diode bars.
