ABSTRACT:
A semiconductor laser device having an array of injection laser diodes with laser cavities coupled to respective inputs of an optical star coupler. The star coupler functions both as a power combiner, to provide a single high-power output, an as a device to couple the laser cavities into a single integrated lasing region, for improved coherence and divergence properties and practically no wavefront distortion.
