Abstract

We have developed an array of ten uncoupled, single-mode ridge-waveguide lasers for spectral beam combining at 980 nm, which are based on an aluminium-free active region. Single emitters deliver 0.4 W CW at 0.7 A with an M² beam quality factor of 1.6. The array has an output power of 2.1 W CW at 3.15 A. The maximum wall-plug efficiency is 48%. Spectral beam combining is achieved through a low-quality-factor external cavity. We extract more than 1.5 W from the cavity with a good beam quality. The ten peak wavelengths range between 968 and 982 nm. The source was validated by pumping an EDFA with similar results as a single wavelength source.
