Miniature ridge waveguide laser, minitype laser and preparation method thereof

Abstract

The invention discloses a miniature ridge waveguide laser, a minitype laser and a preparation method thereof. The miniature ridge waveguide laser and the minitype laser provided by the invention use ridge optical waveguide as gain medium of the laser; the volume of a laser resonant cavity can be reduced; the optical power density in the resonant cavity is improved, so that the stable waveguide laser output can be realized; films are plated at two ends of the waveguide; the use of a lens and reflector is avoided; the number of devices required by the laser is reduced; the size and the cost of the laser are greatly reduced; the integration degree and the stability of the laser system are improved; a soft proton exchange method is used for preparing the miniature ridge waveguide laser; the damage to crystal lattices in crystals is reduced; the laser frequency conversion efficiency is improved; the soft proton exchange temperature is increased to 300 DEG C; on the premise of enabling the crystal phases not to be damaged, the proton exchange and the annealing processes are competed in one step; the preparation process is simplified; the preparation time is shortened.

Description
