Title: Optical system of phase synchronous semiconductor laser array
Inventor: YOSHIDA TOMOHIKO
IPC: H01S3/109
Filed: 1988-01-29
Abstract: PURPOSE:To effectively utilize an output of a phase synchronous semiconductor laser array and to make a visible radiation having a single humped FFP due to a secondary higher harmonic to be generated efficiently, by providing both the phase synchronous semiconductor laser array which is oscillated by two wave surfaces which are 180 deg. out-of-phase, and a diffraction grating coupler which has a period substantially equal to the wavelength of a pair of lights which are half a period out-of-period. CONSTITUTION:The lights emitted from a laser array are converted into parallel rays by a collimator lens 2, and the parallel rays 2 are then applied to a diffraction grating optical coupler 4. In this connection, the laser beams 11, which are made the parallel rays by the collimator lens 2, becomes a double-humped far field pattern(FFP) 12. Two humped FFP components constituting the FFP 12 are applied to diffraction grating couplers 4a and 4b, respectively, which are half a period out-of-period. The light applied from the diffraction grating coupler 4a to an optical waveguide 5a is 180 deg. out of phase with the light applied from the diffraction grating coupler 4b which is half a period out of period with the coupler 4a to an optical waveguide 5b. Therefore, all the lights emitted from the semiconductor laser array 1 are applied to an optical waveguide 5 with being in phase. Thus, secondary higher harmonic lights 13 emitted from the two optical waveguides 5a, 5b are in phase each other, and therefore the FFP becomes a single-humped pattern as indicated by sign 14.
