Title:
WIDE STRIPE DISTRIBUTED BRAGG REFLECTOR LASERS WITH IMPROVED ANGULAR AND SPECTRAL CHARACTERISTICS
Document Type and Number:
WIPO Patent Application WO2000072409
Kind Code:
A3
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.
