Abstract

High power fundamental lateral-mode operation up to 80 mW in CW condition is achieved in a broad-area laser diode. This diode has built-in lens-like effective refractive index distributions in the direction perpendicular to the laser beam. These distributions effectively suppress higher order lateral-mode generation.
