Noticeable good-condition lasers depending on laser crystals are compact and lightweight. Lasers from deep purple to blue are actually noted. Especially, there have been plenty of studies on Pr3+ doped laser crystals, and constant wave lasers about 490 nm are actually realized. Ti∶sapphire is the main attain crystal for ultrafast lasers. Superintense ultrafast lasers with peak electrical power ranging from various hundred terawatts to 10 petawatts involve large-high quality and huge-sized Ti∶sapphire crystal. The origin of defect linked optical absorption in Ti∶sapphire and The expansion of enormous-sized significant-excellent crystals are two significant troubles that urgently must be resolved. Lately, we analyzed the system of defect relevant optical absorption in Ti∶sapphire theoretically, and grew big-sized higher-high quality crystals via warmth Trade process. The most crucial activating ions for one μm laser crystals are Nd3+ and Yb3+. Nd∶YAG will be the most widely employed laser crystal. In recent times, we explored various new Nd3+ doped fluoride and oxide laser crystals, and solved the emission cross area trouble of Nd∶Lu3Al5O12. SIOM reported a brand new type of laser crystal Yb∶GdScO3, of which the attain bandwidth is about 85 nm. The typically utilized activation ions for 2 μm laser crystals are Tm3+ and Ho3+. Tm3+ is often straight pumped by laser diode. Ho3+ has greater stimulated emission cross area, and its emission wavelength is longer than 2 μm. We analyzed the growth, spectroscopy, and laser functionality of Tm∶LiYF4, Tm∶LiLuF4, Ho∶LiYF4, Tm,Ho∶LiYF4, and Tm,Ho∶LiLuF4 crystals.
