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。
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：
GWU delivers all widespread laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) that has a wide range of requirements. Moreover the very well-recognized elements, impressive crystals with remarkable Houses like Yb:CALGO can open new horizons for demanding laser programs. Irrespective of regardless of whether personal pieces for R & D applications are expected or Value-productive figures in compact, medium or large batches with in-time shipping for your production line are wanted: GWU’s devoted service really helps to discover the best Main components for your personal application.
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 illustration, Q-switched lasers attain a higher populace density from the higher laser stage and are therefore additional delicate to quenching results and Electrical power transfer processes; therefore, a reduce doping density is commonly appropriate for these gadgets. For prime-electrical power lasers, reduce doping densities are often used to limit the density of warmth era, Despite the fact that slim-disk lasers get the job done finest with remarkably doped crystals. Quite a few laser products and solutions will not get to the total effectiveness likely due to the fact this kind of particulars have not been properly worked out.
Laser modeling and simulation can be employed to reliably identify the the best possible crystal dimensions, doping density And perhaps values of supplemental parameters.
量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。
It is apparent that distinctive apps cause quite distinct needs on laser acquire media. For this reason, a wide array of various crystals are employed, and creating the right preference is essential for constructing lasers with ideal overall performance.
Distinctive crystalline resources are extremely distinctive regarding their hardness and other Houses, which figure out with which procedures And the way quickly they can be Slice and polished with good quality.
In 2017, we formulated the whole world’s major Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event here of Yb and Tm doped GdScO3 laser crystals with really extensive emission spectra drives the development of laser diode pumped ultrafast strong-state lasers. With the rise in pulse Electrical power, peak ability, and repetition amount of reliable-condition lasers, laser crystals will create towards larger dimensions, increased crystal top quality, and controllable important performance.
There exists a variety of crystalline media, that may be grouped according to important atomic constituents and crystalline structures. Some critical teams of crystals are:
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。
