Description

technical field [0001] The invention belongs to the field of laser materials, in particular to a rhodamine bispyrazole acetate organic laser material. Background technique [0002] Traditional lasers have many problems, such as solid-state lasers, which face problems such as crystal growth difficulties, high technical requirements, and high prices; laser glass generally needs to be melted under high temperature conditions, for different matrix materials and different laser working bands It also needs to remove OH groups and gas protection, the process conditions are harsh, and the production cost is high. At present, more carbon dioxide gas lasers are used. Although the power is high, the devices are bulky and bulky, which brings a lot of inconvenience to occasions that require miniaturized lasers. In recent years, inorganic semiconductor lasers have been developed rapidly and widely used, but there are also problems of high production costs. In view of the limitations in ...
