We report the generation of Airy pulses in an injection-seeded, amplified fiber loop incorporating an acousto-optic frequency shifter and a dispersive delay line implemented through a series combination of linearly chirped fiber Bragg gratings. The combined effect of unidirectional frequency shifting and first-order dispersion generates a frequency comb with cubic spectral phase, equivalent in the time domain to a single-sided, bandlimited Airy pulse train. The present approach demonstrates the use of intra-loop phase-only filtering for the generation of tailorable optical waveforms in recirculating fiber loops.
