Abstract

In the frequency-shifted feedback (FSF) laser, a frequency shift is imposed on a intracavity light field by feedback of the first order diffracted light of an acoustooptic modulator (AOM). There have been several reports on this type of laser with an erbium-doped fiber (EDF) as a gain medium for an electronic tuning of the oscillation wavelength and unidirectional oscillation [1]. Here we report the first obsrevation of a chirped frequency comb output from the EDF-FSF laser and its application to optical reflectometry.
