Low noise and high repetition rate optical frequency combs have been desirable for many applications from timekeeping to precision spectroscopy. With higher

A coherent, compact and robust light source with coverage from the ultraviolet to the infrared is desirable for heterodyne super-resolution imaging1, broadband

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

We report an all-fiber approach to generating sub-2-cycle pulses at 2 µm and a corresponding octave-spanning optical frequency comb. Our configuration leverages

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)
