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。
Laser crystals are optical crystals �?commonly single crystals (monocrystalline optical elements) �?that happen to be used as achieve media for sound-point out lasers. Generally, These are doped with either trivalent uncommon earth ions or changeover metallic ions.
激光晶体（laser crystal），可将外界提供的能量通过光学谐振腔转化为在空间和时间上相干的具有高度平行性和单色性激光的晶体材料。是晶体激光器的工作物质。
This is straightforward to carry out: just find the lock icon before the URL while in the handle bar and drag that for the bookmark toolbar While using the mouse. In case you discover the bookmark entry far too very long, you can proper-click on it to edit the textual content, e.g. applying "RP Enc" rather than "RP Photonics Encyclopedia".
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 area high quality is naturally vital. Specifications of surface flatness are sometimes much better than . This allows to stay away from both scattering losses and wavefront distortions which can degrade the laser's beam high quality. Furthermore, scratch and dig specs
g. a skinny disk. As another illustration, Q-switched lasers reach a better population density from the higher laser level and are for that reason extra delicate to quenching results and Electricity transfer procedures; hence, a reduce doping density is usually appropriate for these units. For prime-electric power lasers, lessen doping densities are often used to limit the density of warmth technology, Despite the fact that slim-disk lasers perform ideal with extremely doped crystals. Lots of laser merchandise do not get to the full efficiency potential click here for the reason that these types of facts have not been effectively 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。
It is obvious that diverse apps bring on pretty different requirements on laser acquire media. Because of this, a broad variety of different crystals are utilised, and producing the correct selection is essential for developing lasers with ideal effectiveness.
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。
For numerous factors, composite crystals are becoming preferred. These Have got a spatially various chemical composition and can be built with Exclusive shapes.
It might be oriented for near perpendicular incidence from the laser beam, or at Brewster's angle. It can be fastened in a few reliable mount which also functions being a heat sink. More substantial crystals are frequently employed for aspect pumping e.g. with superior-ability diode bars.
人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
