Abstract

We report the development of a phase-stable mid-IR Er:fibre laser-amplifier system operating at a 76 MHz repetition rate. A train of ultrashort mid-IR pulses is generated by a difference frequency mixing between a portion of the 1.55-mm output of an Er:fibre master oscillator and a dispersive branch of a supercontinuum driven by the second portion. This scheme yields a high-brightness mid-IR frequency comb with automatically zeroed carrier-envelope offset frequency, motivated by applications in spectroscopy of trace gases and nanophotonics.
