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。

In addition, some overall flexibility is misplaced in experiments if one simply cannot try out absorbers with unique thickness or doping concentration, such as, with no exchanging the laser crystal alone.

Which geometry, dopant and doping focus of your obtain medium are most advantageous depend upon many things. The offered pump resource (variety of laser diode or lamp) plus the envisaged pumping arrangement are important elements, but the material itself also has some impact. One example is, titanium–sapphire lasers must be pumped with high intensities, for which the form of a transversely cooled rod, operated with somewhat small pump and laser beam diameter, is a lot more correct than e.

Not surprisingly, it is extremely attractive that a given crystal good quality is produced constantly, Whilst different laser layouts can have a distinct sensitivity to product parameters.

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。

In 2017, we created the entire world’s major 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 very huge emission spectra drives the event of laser diode pumped ultrafast solid-point out lasers. With the increase in pulse Vitality, peak read more ability, and repetition level of good-point out lasers, laser crystals will establish in the direction of greater sizes, bigger crystal high quality, and controllable essential performance.

There is certainly a wide array of crystalline media, that may be grouped in accordance to important atomic constituents and crystalline constructions. Some important 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。
