Hasler, B. Sumpf, P. Adamiec, J. Fricke, H. Wenzel, G. Erbert, G. Tränkle] Different measures to improve the modulation efficiency of a distributed Bragg reflector tapered diode laser emitting at 1060nm were investigated. Due to the 6-mm long cavity, the device reached an output power of 10W with a nearly diffraction-limited beam quality. The input currents to the ridge-waveguide (RW) and tapered gain-region sections can be independently controlled. This allows a low-current modulation of the optical output power in the Watt range. Under optimized quasi-static conditions the power could be modulated between 0.2 and 3.1W (4.8W) by a variation of the RW current between 0 and 50mA (350mA). Due to the integrated 6th order surface Bragg grating the emission wavelength remains within the spectral range of 80pm.
