Abstract

A solid-state laser generating a green continuous laser and a method thereof are disclosed. The laser comprises a pumping source used for generating 798-801nm pumping light, a light splitting unit, an optical path conversion unit, an Er3+:YAlO3 crystal, a resonant cavity and two Fabry-Perot etalons. The light splitting unit is used for splitting the pumping light into a first light beam and a second light beam. The first light beam is entered into a first end surface of a laser crystal. The second light beam is entered into a second end surface of the laser crystal through the optical path conversion unit. The laser crystal is used for generating up-conversion fluorescence under excitation of the first light beam and the second light beam. The resonant cavity is used for outputting a laser of a green light wave band. The two Fabry-Perot etalons are located in the resonant cavity and are used for compressing a line width of an output laser. The structure of the laser is simple, cost is low and green-light continuous output of a narrow line width is realized. The invention also provides a method of generating the green-light continuous laser. Advantages that output laser beam quality is good; the line width is narrow; optical to optical conversion efficiency is high and so on are possessed.

Description

technical field [0001] The invention relates to the field of solid-state lasers, in particular to a solid-state laser and a method for generating green continuous laser light. Background technique [0002] At present, many types of lasers can achieve continuous laser output in the green band, such as diode lasers, dye lasers, and frequency-doubled lasers. But in general, the quality of the laser beam output by the diode laser is poor. In general, the laser beam quality factor M of the diode laser output directly or via fiber coupling 2 >20. Even with beam shaping, the beam quality factor M of a diode laser 2 Also greater than 2. Dye lasers can also achieve continuous green light output, but the stability of the laser system is not good due to the use of liquid dyes as working substances. Frequency-doubled lasers can also achieve continuous green light output, but the system structure of frequency-doubled lasers is complex and expensive. [0003] Based on the shortco...
