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 acquire medium are most beneficial rely on several components. The offered pump source (variety of laser diode or lamp) plus the envisaged pumping arrangement are essential things, but the fabric itself also has some affect. For example, titanium–sapphire lasers should be pumped with high intensities, for which the form of the transversely cooled rod, operated with fairly compact pump and laser beam diameter, is more acceptable 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。

Obviously, it is extremely attractive that a specified crystal high-quality is generated continually, Despite the fact that distinct laser designs might have a special sensitivity to material parameters.

The maximum probable doping concentration can depend strongly to the host materials and its fabrication system.

激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。

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。

For quasi-a few-degree laser gain media or simply 3-level get media, one particular frequently really should limit the duration to a price that is far too short for effective pump absorption, as reabsorption consequences would in any other case spoil the performance. For aspect pumping, supplemental concerns appear into Participate in; Apart from successful pump absorption, it's important to obtain an appropriate spatial form with the attain profile.

The medium ought to have a significant transparency (reduced absorption and scattering) while in the wavelength areas of pump and laser radiation, and excellent optical homogeneity. To some extent, this relies on the quality of the material, determined by information with the fabrication method.

With that concept, a single doesn't require an additional saturable absorber crystal, so that a person might make extra compact Q-switched laser setups with decreased inner parasitic losses. Nevertheless, unwelcome side Laser Crystal effects may happen, which include obtaining unwelcome valence states with the involved ions or Electrical power transfers.
