Coherent Frequency Combs for Spectroscopy in the 3-5 Micron Region



Daniel I. Maser, Gabriel G. Ycas, William I. Depetri, Flavio Caldas da Cruz, Scott A. Diddams


A tunable mid-infrared frequency comb was created via diff erence frequency generation. Pulses between 1 and 1.5 μm were mixed to make idlers of 2.6-5.2 μm. Two such combs were heterodyned at 5 μm to show their coherence and potential for spectroscopy.
