The most common laser-Energetic rare earth ions and host media together with some standard emission wavelengths are revealed in the following desk:
These ions permit the crystal to amplify mild within the laser wavelength by way of stimulated emission, when Power is equipped on the crystal through 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 with the attain medium are most useful depend on numerous variables. The accessible pump resource (type of laser diode or lamp) plus the envisaged pumping arrangement are important variables, but the fabric itself also has some influence. By way of example, titanium–sapphire lasers should be pumped with substantial intensities, for which the form of the transversely cooled rod, operated with rather little pump and laser beam diameter, is much more ideal than e.
GWU provides all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) by using a broad selection of specs. Apart from the very well-established elements, innovative crystals with remarkable Houses like Yb:CALGO can open new horizons for demanding laser purposes. Irrespective of whether or not person parts for R & D applications are necessary or Value-efficient numbers in tiny, medium or substantial batches with in-time shipping and delivery for the manufacturing line are desired: GWU’s focused assistance helps to locate the ideal Main factors to check here your software.
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 thin disk. As another illustration, Q-switched lasers attain an increased population density while in the upper laser degree and are thus a lot more sensitive to quenching outcomes and Electrical power transfer processes; hence, a lessen doping density is usually appropriate for these units. For high-electric power lasers, reduced doping densities are often accustomed to Restrict the density of warmth technology, although skinny-disk lasers perform finest with very doped crystals. Lots of laser merchandise will not reach the complete functionality prospective since these details have not been adequately 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。
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 apparent that distinctive purposes produce really different demands on laser gain media. This is why, a wide variety of different crystals are made use of, and producing the appropriate choice is important for setting up lasers with ideal functionality.
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 must have a higher transparency (very low absorption and scattering) inside the wavelength areas of pump and laser radiation, and very good optical homogeneity. To some extent, this relies on the quality of the fabric, determined by details of the fabrication process.
With That idea, a single isn't going to will need an extra saturable absorber crystal, so that 1 might make extra compact Q-switched laser setups with lessen inner parasitic losses. However, unwelcome Negative effects may additionally arise, for instance acquiring unwanted valence states in the concerned ions or Vitality transfers.
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。
