Abstract
A diode laser comprises a laser cavity defining a linear optical-path axis, and a current-pumped stripe region, said current-pumped stripe region being disposed within said laser cavity. The laser cavity includes an output surface perpendicular to the optical axis; and a reflection surface including a distributed Bragg reflector (DBR) grating and being disposed at a non-perpendicular angle to the optical-path axis.
Claims7
A diode laser comprising:
- (1) an output surface;
- (2) a reflection surface substantially parallel to, and offset from, said output surface, the output surface and reflection surface defining a laser cavity;
- (3) a first DBR grating with the laser cavity, and disposed 45 degrees to the local longitudinal axis of the laser cavity;
- and
- (4) a second DBR grating within the laser cavity, and disposed at 45 degrees to the laser cavity.
