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。
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and likewise the upper-condition life time.
GWU offers all common laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) which has a broad number of specs. Aside from the properly-proven components, modern crystals with fantastic Homes like Yb:CALGO can open new horizons for demanding laser purposes. It does not matter irrespective of whether particular person pieces for R & D applications are expected or Price-economical figures in small, medium or substantial batches with in-time delivery for that production line are desired: GWU’s committed company helps you to discover the best core parts for your personal application.
A substantial area high quality is naturally vital. Specs of surface area flatness will often be much better than . This allows to prevent the two scattering losses and wavefront distortions which could degrade the laser's beam excellent. Also, scratch and dig requirements
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
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。
For quasi-a few-degree laser gain media or simply 3-level obtain media, just one usually must Restrict the duration to a price which is far too brief for economical pump absorption, as reabsorption results would if not spoil the efficiency. For facet pumping, extra issues occur into Perform; Moreover efficient pump get more info absorption, it is necessary to acquire an appropriate spatial form of your gain 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。
In 2017, we made the entire world’s major Ti∶sapphire crystal (Φ235 mm), which supported the 10 PW laser output of Shanghai Superintense Ultrafast Laser Facility. The development of Yb and Tm doped GdScO3 laser crystals with exceptionally vast emission spectra drives the event of laser diode pumped ultrafast good-state lasers. With the increase in pulse Strength, peak ability, and repetition price of sound-condition lasers, laser crystals will produce to larger sizes, greater crystal top quality, and controllable crucial functionality.
There's an array of crystalline media, which may be grouped in accordance to big atomic constituents and crystalline buildings. Some important groups 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。
