In the frequency-shifted feedback laser (FSF laser), a frequency shift is imposed on an intracavity light field by feedback of the first order diffracted light of an acousto-optic modulator (AOM). Here we report the first observation of a chirped frequency comb output from this type of laser with erbium-doped fiberas a gain medium, and investigate its application to optical reflectometry. The spatial resolution is demonstrated to be 1.5 mm.
