Title:
DUAL-WAVELENGTH RESONANT CAVITY BASED ON VOLUME BRAGG GRATING
Document Type and Number:
WIPO Patent Application WO/2022/083116
Kind Code:
A1
Abstract:
Provided is a dual-wavelength resonant cavity based on a volume Bragg grating, comprising: first to fourth volume Bragg gratings (TVBG1, TVBG2, RVBG3, RVBG4); the first volume Bragg grating (TVBG1) and the second volume Bragg grating (TVBG2) are arranged at intervals; the reflected-light optical path of a third volume Bragg grating (RVBG3) coincides with the diffracted-light optical path of the first volume Bragg grating (TVBG1); the reflected-light optical path of a fourth volume Bragg grating (RVBG4) coincides with the diffracted-light optical path of the second volume Bragg grating (TVBG2); the first volume Bragg grating (TVBG1) and the second volume Bragg grating (TVBG2) are located on the emitted light path of a pumping light; the first volume Bragg grating (TVBG1) and the second volume Bragg grating (TVBG2) output dual wavelength laser light. The volume Bragg gratings serve as reflectors and output mirrors, respectively; using the volume Bragg gratings to coordinate the gain competition between two laser oscillation wavelengths in the resonant cavity achieves stable and balanced dual-wavelength laser light output.
