We demonstrate up to 1.6 Watts of single frequency output from a tapered diode laser operating at 785 nm. The tapered diode laser is used in a rear end external cavity set-up where the external feedback element is a combination of a BaTiO3 phase-conjugating crystal and a high reflection mirror. The set-up presented inherently suppresses the self-wavelength scanning effect, which is well known when employing a phase-conjugating crystal as a dynamic wavelength selection component in a laser cavity. The experimental results have been discussed theoretically in some details by employing a two-beam coupling model.
