High-energy dissipative soliton-driven fiber optical parametric oscillator emitting at 1.7 mu m

摘要

We report a fiber optical parametric oscillator (FOPO) synchronously pumped in a C-band, delivering high-energy picosecond pulses exceeding the nanojoule level of around 1700 nm. The gain medium is a dispersion-shifted fiber, pumped by highly-chirped pulses from a mode-locked dissipative soliton fiber laser. Optimizing the pump wavelength along with time-dispersion-tuning of the FOPO enabled a broad tunability from 1617-1876 nm for the idler wave. In addition, relative intensity noise levels below -140 dBc Hz(-1) have been achieved, paving the way for using such a source in biophotonics and instrumentation.
