Seen reliable-state lasers depending on laser crystals are compact and lightweight. Lasers from deep crimson to blue are described. Specially, there were lots of reports on Pr3+ doped laser crystals, and continual wave lasers all over 490 nm have already been accomplished. Ti∶sapphire is the main get crystal for ultrafast lasers. Superintense ultrafast lasers with peak electrical power ranging from several hundred terawatts to ten petawatts involve higher-quality and huge-sized Ti∶sapphire crystal. The origin of defect linked optical absorption in Ti∶sapphire and The expansion of large-sized higher-high quality crystals are two critical challenges that urgently should be tackled. Recently, we analyzed the system of defect related optical absorption in Ti∶sapphire theoretically, and grew huge-sized substantial-quality crystals via heat Trade system. The key activating ions for one μm laser crystals are Nd3+ and Yb3+. Nd∶YAG is the most widely made use of laser crystal. In recent years, we explored several new Nd3+ doped fluoride and oxide laser crystals, and solved the emission cross area trouble of Nd∶Lu3Al5O12. SIOM reported a brand new style of laser crystal Yb∶GdScO3, of which the attain bandwidth is about 85 nm. The generally made use of activation ions for 2 μm laser crystals are Tm3+ and Ho3+. Tm3+ can be specifically pumped by laser diode. Ho3+ has greater stimulated emission cross section, and its emission wavelength is more time than two μm. We researched The expansion, spectroscopy, more info and laser efficiency of Tm∶LiYF4, Tm∶LiLuF4, Ho∶LiYF4, Tm,Ho∶LiYF4, and Tm,Ho∶LiLuF4 crystals.

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。

亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。

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。

All those surfaces which can be passed via the laser beam are Commonly either oriented at Brewster's angle or have an anti-reflection coating.

Various crystalline materials are really distinctive regarding their hardness and other Homes, which determine with which procedures and how simply they may be Lower and polished with high quality.

The medium ought to have a substantial transparency (reduced absorption and scattering) during the wavelength areas of pump and laser radiation, and good optical homogeneity. To some extent, this will depend on the quality of the fabric, based on information of the fabrication approach.

There may be a variety of crystalline media, which can be grouped according to important atomic constituents and crystalline structures. Some crucial groups of crystals are:

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。
