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。
激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。
Which geometry, dopant and doping focus of your achieve medium are most advantageous depend on various aspects. The accessible pump resource (variety of laser diode or lamp) as well as envisaged pumping arrangement are very important variables, but the material by itself also has some influence. Such as, titanium–sapphire lasers must be pumped with high intensities, for which the form of the transversely cooled rod, operated with rather compact pump and laser beam diameter, is more acceptable than e.
