Methods And Apparatus For Generating Mid-Infrared Frequency Combs

NIST Inventors
Scott Diddams , Scott Papp , Abijith Kowligy and Alexander Lind
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)
