GWU features all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etc.) having a wide range of technical specs. Besides the effectively-recognized materials, ground breaking crystals with remarkable Houses like Yb:CALGO can open new horizons for demanding laser apps. It doesn't matter no matter whether particular person pieces for R & D applications are required or Price tag-effective numbers in smaller, medium or significant batches with in-time shipping for the manufacturing line are required: GWU’s dedicated company helps to find the ideal Main elements for the application.
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。
探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。
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。
For quasi-3-stage laser get media or perhaps 3-amount gain media, a person generally needs to Restrict the length to a worth which is way too brief for efficient pump absorption, as reabsorption consequences would otherwise spoil the performance. For facet pumping, further considerations appear into Engage in; click here Apart from successful pump absorption, it is vital to get a suitable spatial condition of the gain profile.

In 2017, we designed the whole world’s most significant 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 extremely vast emission spectra drives the development of laser diode pumped ultrafast stable-state lasers. With the increase in pulse Power, peak electricity, and repetition level of good-point out lasers, laser crystals will develop towards bigger sizes, greater crystal top quality, and controllable crucial functionality.
There is a wide range of crystalline media, which can be grouped according to important atomic constituents and crystalline structures. Some essential groups 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。
