ABSTRACT
This letter reports on broadband laser sources based on InGaAs tapered diode laser amplifiers with external optical feedback. The generated 920 nm radiation with a bandwidth of up to 20 nm and a power of a few hundred milliwatts is emitted in an almost diffraction limited beam. Spectral filtering and subsequent amplification in a second tapered amplifier provides radiation with spectral widths in the range of 20 to 40 nm and optical output powers of up to 2.5 W.
