The commonest laser-active uncommon earth ions and host media together with some common emission wavelengths are shown in the next table:
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。
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。
作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：
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。
Of course, it is vitally appealing that a provided crystal good quality is made regularly, Despite the fact that distinct laser patterns may have another sensitivity to material parameters.
g. a thin disk. As A further instance, Q-switched lasers get to a higher population density within the higher laser degree and therefore are as a result far more sensitive to quenching results and Electricity transfer processes; thus, a decreased doping density is frequently suitable for these devices. For top-power lasers, decrease doping densities tend to be accustomed to Restrict the density of heat generation, although slender-disk lasers do the job most effective with remarkably doped crystals. Several laser items never reach the comprehensive overall performance possible mainly because these aspects have not been properly labored out.
The host crystal is a lot more than simply a method to repair the laser-Lively ions at selected positions in Area. Several Homes in 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。
For quasi-3-level laser get media and even three-degree achieve media, just one normally has to Restrict the size to a worth which happens to be also short Laser Crystal for effective pump absorption, as reabsorption results would normally spoil the general performance. For side pumping, extra criteria occur into play; In addition to economical pump absorption, it's important to obtain an appropriate spatial shape from the obtain profile.
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。
The medium should have a higher transparency (low absorption and scattering) while in the wavelength areas of pump and laser radiation, and excellent optical homogeneity. To some extent, this relies on the caliber of the fabric, based on details with the fabrication system.
Working with our promotion bundle, you are able to Screen your emblem, even more underneath your solution description, and these will been found by several photonics experts.
