  • Patent number: 11364078
    Abstract: The present disclosure discloses an electro-optic Q-switching double-frequency double-pulse laser lithotripsy system. The system includes a total reflection mirror, an electro-optic Q-switching assembly, a drive circuit, a controller, a pump source, a gain medium, an output mirror, a first focusing mirror, a frequency doubling crystal, a second focusing mirror, a coupling lens and an output optical fiber; the electro-optic Q-switching assembly and the gain medium are located between the total reflection mirror and the output mirror; and the controller controls the pump source to work, and controls a voltage of the electro-optic Q-switching assembly by controlling the drive circuit, so that the system outputs a double-frequency laser beam with a pulse width of 1-1.5 ?s or 200-300 ?s.
