All-fiber ultrashort similariton generation, amplification, and compression at telecommunication band

Abstract

We experimentally demonstrate an all-fiber ultrashort pulse amplification and compression system seeded by similaritons at an erbium-doped wavelength band. By optimizing the compressor, our system can generate 4.1 nJ, 75.6 fs pedestal-free pulses with 54 kW peak power. The corresponding spectrum width is 51 nm and has no spectral spikes. Such high-quality ultrashort pulses benefit from the linear chirp of similaritons. Furthermore, we experimentally demonstrate the variation of the similariton spectral width and compressed pulse duration to the amplifier gain, which is consistent with theoretical study.
