摘要
We characterize a new mid-infrared frequency comb generator based on difference frequency generation around 3.1 mu m. High power per comb mode (> 10(-7) W/mode) is obtained over a broad spectral span (> 750 nm, > 790 cm(-1)). The source is used for direct absorption spectroscopy with a Michelson-based Fourier transform interferometer.
