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 with the get medium are most advantageous rely on numerous things. The accessible pump source (sort of laser diode or lamp) as well as envisaged pumping arrangement are very important things, but the fabric by itself also has some influence. Such as, titanium–sapphire lasers need to be pumped with superior intensities, for which the form of the transversely cooled rod, operated with reasonably little pump and laser beam diameter, is a lot more proper than e.

激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
The maximum doable doping concentration can rely strongly around the host substance and its fabrication technique.
Several laser crystal products are already demonstrated wherever some saturable absorber more info materials is integrated for passive Q switching of the laser.
量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。

The medium must have a large transparency (low absorption and scattering) from the wavelength regions of pump and laser radiation, and superior optical homogeneity. To some extent, this is dependent upon the quality of the material, based on specifics of your fabrication method.
It might be oriented for around perpendicular incidence on the laser beam, or at Brewster's angle. It could be fastened in a few reliable mount which also acts like a heat sink. Bigger crystals are often used for facet pumping e.g. with significant-electricity diode bars.
人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
