Generation of pedestal-free 10 GHz pulses from a comb-like dispersion profiled fiber compressor and its application in supercontinuum generation

We built a pulse compressor using a. comb-like dispersion-profiled fiber fi ber (CDPF). The CDPF consists of 12-segment fibers with the dispersion alte rnatively high and low. Using this compressor and a 17 dBm Erbium-doped,cd fiber amplifier, the 10 GHz, 12 ps pulses generated from an actively mode-l ocked Er3+ doped fiber ring laser was compressed to similar to2 ps without pedestal. We also show that compared with the high order soliton pulse comp ressor, the power efficiency can be doubled in supercontinuum generation by using the primp pulses compressed by this CDPF compressor.
