Abstract

High-brightness narrow line-width 1060 nm tapered lasers with an internal distributed Bragg reflector were realized. The devices reach a maximal output power of 12 W with a narrow spectral line-width below 40 pm (95% power). A nearly diffraction limited beam quality was measured up to a power of 10 W. The vertical structure is based on an InGaAs triple quantum well (TQW) active region embedded in a 4.8 μm broad AlGaAs super large optical cavity. This leads to a narrow vertical divergence of 15° (FWHM). Tapered devices were processed a total length of 6 mm consisting of 2 mm long ridge waveguide (including 1 mm DBR mirror) and 4 mm tapered sections. A full taper angle of 6° was manufactured. The input currents to both sections can be independently controlled. The devices had a conversion efficiency of about 50%. A first reliability test showed failure-free operation at 5 W without a deterioration of the beam quality and the spectral properties.
