We report theoretical results on the wavelength stabilization in
distributed-feedback master-oscillator power-amplifiers which are compact
semiconductor laser devices capable of emitting a high brilliance beam at an
optical power of several Watts. Based on a traveling wave equation model we
calculate emitted optical power and spectral maps in dependence on the pump
of the power amplifier. We show that a proper choice of the Bragg grating
type and coupling coefficient allows to optimize the laser operation, such
that for a wide range of injection currents the laser emits a high intensity
continuous wave beam.
