Which geometry, dopant and doping concentration in the obtain medium are most beneficial count on several factors. The accessible pump source (type of laser diode or lamp) as well as the envisaged pumping arrangement are very important variables, but the material alone also has some impact. Such as, titanium–sapphire lasers ought to be pumped with significant intensities, for which the form of the transversely cooled rod, operated with comparatively small pump and laser beam diameter, is much more suitable 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。
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。
Laser modeling and simulation can be used to reliably establish the the best possible crystal dimensions, doping density And maybe values of more parameters.
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。
It is clear that distinctive applications result in incredibly different specifications on laser acquire media. Because of this, a broad click here variety of different crystals are used, and making the right preference is important for setting up lasers with optimum performance.

In 2017, we formulated 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 extremely huge emission spectra drives the event of laser diode pumped ultrafast strong-condition lasers. With the rise in pulse Electrical power, peak electrical power, and repetition fee of good-state lasers, laser crystals will create in direction of larger sized dimensions, larger crystal high-quality, and controllable key efficiency.
It might be oriented for in close proximity to perpendicular incidence of the laser beam, or at Brewster's angle. It can be mounted in a few reliable mount which also functions for a warmth sink. Larger sized crystals are usually used for side pumping e.g. with high-energy diode bars.
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。
