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 gain medium are most advantageous depend on a number of factors. The offered pump source (sort of laser diode or lamp) and the envisaged pumping arrangement are very important things, but the material alone also has some influence. By way of example, titanium–sapphire lasers should be pumped with higher intensities, for which the shape of the transversely cooled rod, operated with fairly small pump and laser beam diameter, is much more suitable than e.

Obviously, it is very attractive that a specified crystal high-quality is generated persistently, Though different laser models may have a different 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。
The host crystal is considerably more than simply a means to fix the laser-Lively ions at certain positions in Area. Quite a few Attributes from the host materials are essential:
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。
For quasi-3-level laser gain media or maybe 3-amount achieve media, a single typically needs to limit the duration to a price which is way too short more info for successful pump absorption, as reabsorption effects would in any other case spoil the performance. For side pumping, more concerns arrive into Enjoy; Aside from productive pump absorption, it's important to get an acceptable spatial condition from the obtain profile.

In 2017, we produced the whole world’s greatest 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 exceptionally wide emission spectra drives the development of laser diode pumped ultrafast sound-condition lasers. With the increase in pulse Electricity, peak power, and repetition price of strong-state lasers, laser crystals will create in the direction of greater sizes, greater crystal top quality, and controllable crucial efficiency.
It could be oriented for in the vicinity of perpendicular incidence of your laser beam, or at Brewster's angle. It might be fastened in a few solid mount which also functions to be a warmth sink. More substantial crystals are frequently utilized for facet pumping e.g. with superior-electric power diode bars.
