Abstract

We report on distributed Bragg reflector tapered lasers having 6^th order surface gratings and ridge waveguides simultaneously fabricated by wafer stepper lithography and reactive ion etching. Single longitudinal mode emission at 978 nm and a beam propagation ratio of M² = 1.1 at 4.4 W have been obtained in quasi-continuous wave operation. In CW operation, a maximal output power of 2.5 W with a side-mode suppression ratio of more than 20 dB and a beam propagation ratio of M² < 1.4 for the central lobe has been achieved.
