Injection locking characteristics of a 1 W broad stripe laser diode

· Appl. Phys. Lett.; (United States)
Single narrow far-field lobe emission is observed in an injection-locked high-power broad stripe laser. Lobe widths below 1.3 times the diffraction limit for the 160-..mu..m-wide stripe were observed for power levels up to 1.0 W. Decrease in the power contained within the narrow lobe for high laser bias currents is observed and is attributed to self-focusing effects in the active region. Small-signal external power gain of 21 dB was measured.
