Abstract

The invention discloses an F-P configuration Q-switched frequency-doubled laser. The F-P configuration Q-switched frequency-doubled laser comprises a laser working medium and an F-P standard Q-switched frequency-doubled device, wherein the F-P standard Q-switched frequency-doubled device is arranged behind the laser working medium and manufactured from crystals with an electrostrictive effect and a frequency-doubled optical effect; an electrostrictive direction of the F-P standard Q-switched frequency-doubled device coincides with a frequency-doubling direction corresponding to fundamental frequency laser at the F-P standard Q-switched frequency-doubled device; when the electrostrictive length of the F-P standard Q-switched frequency-doubled device meets a Fabry-Perot interference condition of the fundamental frequency laser, the fundamental frequency laser generated by the laser working medium passes through the F-P standard Q-switched frequency-doubled device in the frequency-doubling direction; and when the power density of the fundamental frequency laser exceeds a frequency-doubling conversion threshold, the fundamental frequency laser is generated in the F-P standard Q-switched frequency-doubled device and is output. According to the F-P configuration Q-switched and frequency-doubled laser, the technical indexes of an electric system can be effectively reduced, the modulation frequency of the electric system is increased, the design of the electric system is simplified, and the purpose of miniaturization of the electric system is achieved.

Description

technical field [0001] The invention relates to an F-P configuration Q-switched frequency-multiplied laser, belonging to the technical field of lasers. Background technique [0002] At present, Q-switched frequency doubling laser is one of the important technologies for laser applications. For a long time, due to the high voltage required for electro-optic modulation, the servo electrical system of electro-optic Q-switched laser has high technical indicators, difficult design, high insulation difficulty, strict requirements on electro-optic crystals, and the production of high-performance electro-optic Q-switched devices is extremely difficult. . These make the compact and miniaturized design of Q-switched lasers face a lot of obstacles, and the design of Q-switched devices with simple structure and low requirements for electrical servo systems has become an urgent need for laser application expansion. Contents of the invention [0003] The technical problem to be solved...
