Obvious good-condition lasers based upon laser crystals are compact and light-weight. Lasers from deep red to blue happen to be claimed. In particular, there were loads of studies on Pr3+ doped laser crystals, and continuous wave lasers all over 490 nm have already been realized. Ti∶sapphire is the principle gain crystal for ultrafast lasers. Superintense ultrafast lasers with peak ability ranging from many hundred terawatts to 10 petawatts have to have higher-excellent and enormous-sized Ti∶sapphire crystal. The origin of defect associated optical absorption in Ti∶sapphire and the growth of enormous-sized significant-high-quality crystals are two essential troubles that urgently must be dealt with. Lately, we analyzed the mechanism of defect relevant optical absorption in Ti∶sapphire theoretically, and grew big-sized large-top quality crystals by way of heat exchange method. The main activating ions for one μm laser crystals are Nd3+ and Yb3+. Nd∶YAG will be 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 portion challenge of Nd∶Lu3Al5O12. SIOM documented a brand new type of laser crystal Yb∶GdScO3, of which the get bandwidth is about 85 nm. The commonly applied activation ions for 2 μm laser crystals are Tm3+ and Ho3+. Tm3+ could be straight pumped by laser diode. Ho3+ has bigger stimulated emission cross part, and its emission wavelength is for a longer time than two μm. We studied The expansion, spectroscopy, and laser overall performance of Tm∶LiYF4, Tm∶LiLuF4, Ho∶LiYF4, Tm,Ho∶LiYF4, and Tm,Ho∶LiLuF4 crystals.
