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.

Abstract: An apparatus includes a single-mode master-oscillator section and a power amplifier section. The single-mode master-oscillator section includes a waveguide defined by a first end and a second end, the first end including a first distributed Bragg reflector mirror, and the second end including a second distributed Bragg reflector mirror. The single-mode-master-oscillator section also has a first longitudinal axis. The power amplifier section is a broad-contact amplifier coupled to the single-mode-master-oscillator section by a coupling grating that is contained in the waveguide of the single-mode-master-oscillator section. The broad contact amplifier section includes a reflection side, an output side and a second longitudinal axis, the second longitudinal axis being at an angle approximately (90°−&bgr;) to said first longitudinal axis, &bgr; being in a range between 0° and approximately 20°.
