Which geometry, dopant and doping concentration with the acquire medium are most useful rely on quite a few aspects. The out there pump supply (variety of laser diode or lamp) as well as the envisaged pumping arrangement are crucial elements, but the material alone also has some impact. By way of example, titanium–sapphire lasers should be pumped with higher intensities, for which the shape of the transversely cooled rod, operated with reasonably small pump and laser beam diameter, is a lot more ideal 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 figure out the ideal crystal Proportions, doping density and possibly values of extra parameters.

In 2017, we developed the planet’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 extremely broad emission spectra drives the development of laser diode pumped ultrafast solid-state lasers. With the increase in pulse Vitality, peak power, and repetition rate of solid-state lasers, laser crystals will produce to much larger dimensions, better crystal quality, and controllable critical functionality.
You can find a wide range of crystalline media, which may be grouped in accordance to special atomic constituents and crystalline constructions. Some critical teams of crystals are:
