Obvious stable-condition lasers determined by laser crystals are compact and light. Lasers from deep pink to blue are actually described. Particularly, there have been a great deal of reviews on Pr3+ doped laser crystals, and continual wave lasers all around 490 nm happen to be realized. Ti∶sapphire is the key attain crystal for ultrafast lasers. Superintense ultrafast lasers with peak electric power starting from numerous hundred terawatts to 10 petawatts require higher-high-quality and large-sized Ti∶sapphire crystal. The origin of defect connected optical absorption in Ti∶sapphire and The expansion of enormous-sized superior-quality crystals are two crucial difficulties that urgently should be dealt with. Recently, we analyzed the system of defect similar optical absorption in Ti∶sapphire theoretically, and grew huge-sized substantial-excellent crystals by warmth exchange approach. The key activating ions for 1 μm laser crystals are Nd3+ and Yb3+. Nd∶YAG is the most widely utilized laser crystal. In recent years, we explored quite a few new Nd3+ doped fluoride and oxide laser crystals, and solved the emission cross part dilemma of Nd∶Lu3Al5O12. SIOM described a whole new form of laser crystal Yb∶GdScO3, of which the obtain bandwidth is about eighty five nm. The frequently utilized activation ions for two μm laser crystals are Tm3+ and Ho3+. Tm3+ may be instantly pumped by laser diode. Ho3+ has more substantial stimulated emission cross segment, and its emission wavelength is for a longer period than 2 μm. We analyzed The expansion, spectroscopy, and laser overall performance of Tm∶LiYF4, Tm∶LiLuF4, Ho∶LiYF4, Tm,Ho∶LiYF4, and Tm,Ho∶LiLuF4 crystals.

主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。
The medium should have a superior transparency (lower absorption and scattering) within the wavelength locations of pump and laser radiation, and excellent optical homogeneity. To some extent, this depends on the caliber of the fabric, determined by facts from the fabrication course of action.
There is a wide range of crystalline media, which can be grouped according to special atomic constituents and crystalline buildings. Some critical groups of crystals are:
