Paper Abstract

We report on the development of high peak-power laser diodes emitting in the 1.5 µm wavelength band. Two design approaches, broad-area laser diodes and tapered laser diodes, are described, both with integrated wavelength locking using distributed Bragg reflector. The peak output power of the broad-area components and tapered components is 6.1 W and 4.6 W, respectively. The output spectra of both component types are narrow with less than 0.3 nm full width at half-maximum, and due to the grating the emission wavelength is resistant to drift caused by temperature changes.
