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 with the get medium are most beneficial depend upon numerous components. The out there pump supply (form of laser diode or lamp) as well as the envisaged pumping arrangement are essential factors, but the fabric by itself also has some influence. Such as, titanium–sapphire lasers should be pumped with large intensities, for which the shape of a transversely cooled rod, operated with relatively smaller pump and laser beam diameter, is more appropriate than e.
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。
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。

In 2017, we made the entire world’s more info major 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 particularly wide emission spectra drives the development of laser diode pumped ultrafast sound-point out lasers. With the rise in pulse energy, peak electrical power, and repetition fee of stable-point out lasers, laser crystals will develop in the direction of greater measurements, increased crystal excellent, and controllable critical general performance.
It may be oriented for close to perpendicular incidence in the laser beam, or at Brewster's angle. It could be preset in some strong mount which also functions being a heat sink. Greater crystals are frequently utilized for side pumping e.g. with high-ability diode bars.
