Paper Abstract

Compact high power laser light sources emitting a single frequency with diffraction limited beams in continuous wave (CW) operation are required for many applications including frequency conversation. We present a hybrid integrated package consisting of a distributed feedback ridge-waveguidemaster-oscillator power- amplifier mounted on an AlN micro-optical bench with a CW output power of 4.5W at 976 nm having a beam propagation ratio of M2 < 2 (including second order moments). The longitudinal mode emission has a linewidth of λ < 10 pm. Due to thermal decoupling the wavelength shift is nearly independent of the amplifier pump-current.
