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。

Which geometry, dopant and doping focus from the obtain medium are most advantageous rely on numerous aspects. The obtainable pump source (type of laser diode or lamp) and the envisaged pumping arrangement are crucial elements, but the fabric by itself also has some influence. Such as, titanium–sapphire lasers should be pumped with large intensities, for which the form of a transversely cooled rod, operated with rather compact pump and laser beam diameter, is more acceptable than e.

晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。

Of course, it is vitally attractive that a presented crystal excellent is developed consistently, Whilst unique laser patterns can have a unique sensitivity to content 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。

It is clear that different applications result in really distinct necessities on laser achieve media. This is why, a broad array of various crystals are utilised, and generating the best decision is essential for developing lasers with the best possible effectiveness.

In 2017, we made the entire world’s largest 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 exceptionally wide emission spectra drives the event of laser diode pumped ultrafast solid-condition lasers. With the increase in pulse Vitality, peak ability, and repetition price of sound-condition lasers, laser crystals will acquire to larger sizes, greater crystal top quality, and controllable key overall performance.

With that concept, 1 doesn't require an read more additional saturable absorber crystal, so that one may perhaps make extra compact Q-switched laser setups with decreased interior parasitic losses. Nonetheless, unwelcome Uncomfortable side effects may additionally manifest, including obtaining undesired valence states from the included ions or Power transfers.

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。
