Abstract
A 1.5-W continuous-wave power output in a beam pattern of 3/spl deg/ is obtained from a new designed rhombus-like stripe strained quantum-well diode laser (/spl lambda/=980 nm) with a 150-/spl mu/m-wide emission aperture grown by molecular beam epitaxy. The /spl eta//sub d/ is as high as 78%, and the maximum output power by the new stripe laser is 5.0 W for antireflection/high-reflection coated devices.
