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。

Which geometry, dopant and doping focus on the achieve medium are most beneficial depend upon many variables. The offered pump supply (kind of laser diode or lamp) and also the envisaged pumping arrangement are important things, but the fabric itself also has some influence. For example, titanium–sapphire lasers ought to be pumped with significant intensities, for which the form of the transversely cooled rod, operated with comparatively little pump and laser beam diameter, is a lot more proper 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。

Laser modeling and simulation can be employed to reliably establish the the best possible crystal dimensions, doping density And maybe values of further parameters.

For quasi-three-amount laser achieve media and even a few-degree gain media, just one usually needs to limit the duration to a value which happens to be also short for productive pump absorption, as reabsorption consequences would in any other case spoil the performance. For aspect pumping, more factors appear into play; Moreover efficient pump absorption, it is vital to get an appropriate spatial condition of your gain profile.

In 2017, we created the whole world’s greatest Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The event of Yb and Tm doped GdScO3 laser crystals with incredibly huge emission spectra drives the event of laser diode pumped ultrafast sound-condition lasers. With the rise in pulse Electrical power, peak energy, and repetition fee of good-point out lasers, laser crystals will create in the direction of more substantial measurements, better crystal high quality, and controllable crucial functionality.

It could be oriented for near perpendicular incidence from the laser beam, or at Brewster's angle. It may be set in some strong mount which also acts to be a warmth sink. Larger sized crystals tend to be useful for aspect pumping e.g. with substantial-electricity check here diode bars.
