We demonstrate 10 GHz mid-infrared frequency combs spanning 3-5 μm and 7-11 μm that are generated with few-cycle electro-optic pulses and intrapulse difference

Apparatus and methods for generating mid-IR frequency combs using intra-pulse DFG. A mode-locked pulse generation laser generates near-IR pulses which are amplified. The amplified pulses are spectrally broadened by a nonlinear element, for example a normal dispersion highly nonlinear fiber (ND-HNLF)
