Below you could post issues and comments. In terms of they get approved via the writer, they'll seem previously mentioned this paragraph together with the author’s respond to. The author will decide on acceptance depending on specified standards. Essentially, the issue should be of sufficiently wide desire.
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。
Which geometry, dopant and doping concentration of the gain medium are most useful rely upon various variables. The available pump source (variety of laser diode or lamp) as well as envisaged pumping arrangement are crucial aspects, but the material alone also has some impact. For instance, titanium–sapphire lasers have to be pumped with superior intensities, for which the form of the transversely cooled rod, operated with rather compact pump and laser beam diameter, is more appropriate 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。
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
g. a skinny disk. As A different illustration, Q-switched lasers achieve the next inhabitants density in the upper laser level and therefore are as a result far click here more delicate to quenching outcomes and Electricity transfer procedures; thus, a decreased doping density is frequently suitable for these units. For high-energy lasers, reduce doping densities are frequently used to limit the density of warmth technology, Despite the fact that slim-disk lasers operate ideal with very doped crystals. Numerous laser goods do not get to the whole effectiveness probable due to the fact this sort of particulars haven't been appropriately worked 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。

The medium ought to have a large transparency (lower absorption and scattering) from the wavelength locations of pump and laser radiation, and superior optical homogeneity. To some extent, this depends on the standard of the fabric, based on aspects with the fabrication course of action.
It may be oriented for around perpendicular incidence of the laser beam, or at Brewster's angle. It can be set in certain solid mount which also acts like a warmth sink. Bigger crystals are often useful for side pumping e.g. with superior-ability diode bars.
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。
