Pulse-train multiplication based on the temporal Talbot effect in a linearly chirped fiber Bragg grating has been experimentally demonstrated. A 40-GHz repetition-rate, nearly transform-limited 10-ps duration optical pulse train at 1.533 μm has been obtained from a 2.5-GHz mode-locked Er– Yb:glass laser by use of a 100-cm-long linearly chirped apodized fiber grating.
