The most common laser-active exceptional earth ions and host media together with some regular emission wavelengths are revealed in the subsequent desk:
Listed here you can submit inquiries and opinions. As far as they get acknowledged with the creator, they will appear higher than this paragraph along with the writer’s response. The creator will determine acceptance based on sure conditions. Fundamentally, the issue needs to be of adequately broad interest.
激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。
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。
Which geometry, dopant and doping concentration from the obtain medium are most advantageous rely on various components. The out there pump resource (variety of laser diode or lamp) plus the envisaged pumping arrangement are very important aspects, but the material by itself also has some influence. Such as, titanium–sapphire lasers should be pumped with high intensities, for which the shape of a transversely cooled rod, operated with rather modest pump and laser beam diameter, is more ideal than e.
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。
活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。
g. a thin disk. As A different example, Q-switched lasers access an increased population density in the higher laser stage and so are thus additional delicate to quenching outcomes and Electrical power transfer procedures; therefore, a lower doping density is commonly suitable for these products. For top-ability lasers, lessen doping densities tend to be used to Restrict the density of warmth era, Though thin-disk lasers function best with really doped crystals. A lot of laser items do not get to the complete general performance probable because these particulars haven't 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。
It is obvious that diverse apps cause incredibly distinctive prerequisites on laser obtain media. For that reason, a broad selection of different crystals are utilised, and creating the correct decision is essential for constructing lasers with the best possible effectiveness.
Different crystalline materials are certainly unique about their hardness and also other properties, which establish with which methods And the way conveniently they can be Minimize and polished with top quality.
For different motives, composite crystals have become well-known. These Possess a spatially varying chemical composition and will be created with Particular shapes.
It may be oriented for near perpendicular incidence from the laser beam, or at Brewster's angle. It may be set in some sound mount which also acts being a heat sink. Greater crystals are frequently utilized for side pumping e.g. with high-power diode check here 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。
