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（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 in addition the upper-condition life span.
GWU features all prevalent laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) that has a broad a number of requirements. Moreover the very well-proven materials, ground breaking crystals with superb Houses like Yb:CALGO can open new horizons for demanding laser applications. Regardless of whether or not person pieces for R & D applications are expected or Expense-effective quantities in modest, medium or huge batches with in-time shipping with the creation line are desired: GWU’s dedicated provider really helps to find the greatest core parts for your application.
A significant area high-quality is obviously critical. Requirements of floor flatness are often better than . This allows to avoid each scattering losses and wavefront distortions which could degrade the laser's beam excellent. Also, scratch and dig requirements
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。
Laser modeling and simulation may be used to reliably determine the ideal crystal Proportions, doping density and possibly values of more parameters.
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。
It is clear that click here distinct purposes result in quite different demands on laser obtain media. Because of this, a wide assortment of different crystals are made use of, and producing the correct option is important for setting up lasers with optimum general performance.

In 2017, we produced the planet’s major Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with exceptionally extensive emission spectra drives the development of laser diode pumped ultrafast stable-point out lasers. With the increase in pulse Power, peak power, and repetition charge of reliable-point out lasers, laser crystals will establish to larger sizes, higher crystal quality, and controllable key overall performance.
There may be a variety of crystalline media, which may be grouped in accordance to special atomic constituents and crystalline constructions. Some crucial teams 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。
