Optical frequency comb (OFC) spectroscopy in the mid-infrared (MIR) promises faster, more precise, or more sensitive molecular spectroscopy. To date, demonstrations of MIR OFCs have suffered from low power, poor wavelength coverage, or low sensitivity. Systems that do excel in these areas have high cost and complexity. The technique and measurements reported here demonstrate that singly resonant, single frequency optical parametric oscillators (OPO’s) are a powerful platform for generating MIR OFC’s with properties not shown by other MIR light sources.
