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 focus on the get medium are most beneficial count on a number of things. The readily available pump source (kind of laser diode or lamp) as well as the envisaged pumping arrangement are important factors, but the fabric itself also has some impact. Such as, titanium–sapphire lasers should be pumped with large intensities, for which the form of a transversely cooled rod, operated with fairly tiny pump and laser beam diameter, is more correct than e.

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 get to a higher populace density during the upper laser degree and so are thus much more sensitive to quenching results and Electricity transfer procedures; therefore, a reduce doping density is commonly suitable for these devices. For high-electrical power lasers, decrease doping densities in many cases are utilized to Restrict the density of warmth era, Though skinny-disk lasers work best with highly doped crystals. Many laser products do not get to the entire effectiveness opportunity for the reason that these information have not been thoroughly 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。
热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。

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。
GWU-Lasertechnik has over 30 several years of working experience in distributing laser crystals. Choose GWU to take advantage of our extensive know-how As well as in-discipline knowledge!
With That idea, one does not require an additional saturable absorber crystal, check here so that 1 may make more compact Q-switched laser setups with lower interior parasitic losses. On the other hand, undesirable Unwanted effects can also happen, which include getting undesirable valence states of the included ions or Power transfers.
