These tables consist of only the most typical host crystals; numerous others exist, that are less regularly made use of.
These ions permit the crystal to amplify light-weight with the laser wavelength through stimulated emission, when energy is equipped into the crystal by means of absorption of pump light-weight (�?optical pumping
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 from the obtain medium are most advantageous count on numerous elements. The readily available pump resource (sort of laser diode or lamp) along with the envisaged pumping arrangement are very important variables, but the fabric by itself also has some impact. As an example, titanium–sapphire lasers ought to be pumped with significant intensities, for which the shape of the transversely cooled rod, operated with somewhat compact pump and laser beam diameter, is more proper 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 An additional example, Q-switched lasers reach a greater populace density while in the higher laser level and so are thus additional sensitive to quenching results and Power transfer processes; hence, a decrease doping density is often suitable for these devices. For prime-power lasers, decreased doping densities in many cases are utilized to limit the density of warmth generation, Whilst thin-disk lasers function most effective with very doped crystals. Lots of laser items don't reach the total general performance possible since these facts have not been thoroughly worked out.
Laser modeling and simulation can be used to reliably figure out the the best possible crystal dimensions, doping density And perhaps values of more parameters.

It is clear that check here diverse purposes cause really unique demands on laser get media. For this reason, a broad assortment of various crystals are employed, and earning the correct preference is essential for setting up lasers with ideal general performance.
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 greater than thirty many years of expertise in distributing laser crystals. Select GWU to gain from our vast know-how and in-subject working experience!
You can find a wide array of crystalline media, that may be grouped according to big atomic constituents and crystalline constructions. Some significant teams of crystals are:
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。
