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 transition cross-sections of pump and laser transitions in addition to the higher-condition lifetime.
GWU features all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etc.) using a wide selection of specs. Aside from the effectively-recognized resources, modern crystals with superb Homes like Yb:CALGO can open new horizons for demanding laser apps. It does not matter whether or not person parts for R & D purposes are demanded or cost-effective quantities in little, medium or large batches with in-time shipping and delivery with the generation line are necessary: GWU’s dedicated provider really helps to find the best core components for your personal 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。
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。
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。
For quasi-3-stage laser get media or even 3-amount gain media, just one frequently needs to Restrict the length to a worth that's check here as well limited for economical pump absorption, as reabsorption consequences would if not spoil the efficiency. For facet pumping, further issues come into Enjoy; besides economical pump absorption, it is vital to get a suitable spatial condition on the acquire profile.

In 2017, we formulated 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 event of Yb and Tm doped GdScO3 laser crystals with extremely vast emission spectra drives the event of laser diode pumped ultrafast stable-state lasers. With the increase in pulse Power, peak power, and repetition charge of sound-state lasers, laser crystals will establish to larger sizes, larger crystal high-quality, and controllable key performance.
It could be oriented for around perpendicular incidence on the laser beam, or at Brewster's angle. It may be fastened in certain solid mount which also acts as being a warmth sink. Bigger crystals usually are useful for facet pumping e.g. with superior-electricity diode bars.
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。
