For the first time, we demonstrate diode lasers consisting of a single quantum-well, which emit at 1156 nm. Ridge waveguide lasers and tapered lasers of this structure contain a monolithically integrated distributed Bragg reflector grating. Step-stress tests of both laser types demonstrate long lifetimes. The radiation of the laser sources is utilized for second-harmonic generation in a single-pass configuration with a 15.5 mm long MgO-doped periodically poled LiNbO3 ridge waveguide crystal. Optical output powers of up to 0.86 W are achieved at 578 nm.
