Microchip ridge waveguide laser, tunable laser and preparation method of microchip ridge waveguide laser

Abstract

The invention discloses a microchip ridge waveguide laser, a tunable laser and a preparation method of the microchip ridge waveguide laser. According to the microchip ridge waveguide laser, by takinga ridge-shaped optical waveguide as a gain medium of the laser, the volume of a laser resonant cavity can be reduced, and the optical power density in the laser resonant cavity can be increased, so that the stable waveguide output can be realized; a traditional piezoelectric ceramic control manner is replaced with a temperature control manner, so that the disadvantage that a microchip is easily damaged through pressure control is overcome, and the microchip ridge waveguide laser has the advantages of high reliability and large wavelength turning range; the microchip ridge waveguide laser is prepared by virtue of a soft proton exchange method, so that the damage caused to lattices in crystals is reduced, and the laser frequency conversion efficiency is improved; and the microchip is prepared from waveguide, and two ends of the microchip are coated with films, so that a lens and a reflection mirror are not used, the numbers of components and parts required by the laser are reduced, the size and cost of the laser are greatly lowered, and the integration level and stability of a laser system can be improved.
