Patent ID: 6904068

Claim:
A semiconductor laser device comprising; a plurality of laser light oscillators that each emit a laser beam from a respective outlet; a diffraction grating with vertical and horizontal grooves that cross each other and that at least partially directs a sufficient portion of a laser beam from the plurality of laser light oscillators to enter another of the plurality of laser light oscillators to enable a phase locking of the respective laser light oscillators while transmitting the remaining portion of the laser beam, when the respective outlets of the laser light oscillators are aligned with the diffraction grating to enable each one of the laser light oscillators to receive at least a portion of the laser beam from another of the plurality of laser light oscillators to enable a phase locking of each one of the plurality of laser light oscillators, and one or more condenser lenses, wherein the one or more condenser lenses receives the laser beam emitted from an outlet portion of the diffraction grating and the diffracting grating is positioned optically between the plurality of laser light oscillators and the one or more condenser lenses.
