High-power uncooled 975-nm Bragg grating stabilized thick-quantum-well lasers

Coherence-collapse operation of a Bragg grating stabilized thick-quantum-well laser diode yields 975-nm wavelength emission with >40 dB side-mode-suppression ratio, 1% power variation, and fiber-output power as high as 293 mW at 15/spl deg/C and 167 mW at 115/spl deg/C.
