Abstract :
Wide stripe SBA lasers with modal reflector have been developed. Extremely narrow single-lobed far-field patterns for the lateral direction are observed up to 0.3 W under CW (continuous-wave) conditions and 0.4 W under pulsed conditions. A simple theoretical model for describing the mode profile is calculated with the model. Good agreement between experimental and calculated far-field patterns is obtained.<>
