Paper Abstract

Nearly diffraction-limited emission from a distributed Bragg reflector (DBR) tapered diode laser is presented. Intrinsic wavelength stabilization is achieved with a 3rd order DBR grating manufactured by electron beam lithography. At a heatsink temperature of 15°C an optical output power of 12.7 W with an electro-optical efficiency > 40% is obtained. The corresponding emission wavelength is 1030.57 nm and spectral bandwidths of 0.02 nm are measured over the whole power range. At 10.5 W of optical power 8.1 W are contained in the central lobe. The measured beam propagation ratio and brightness are 1.1 (1/e2) and 700 MWcm-2 sr-1, respectively. With these parameters, the laser is suitable for applications such as non-linear frequency conversion.
