Ultrafast dual-comb spectroscopyAn artistic image of a dual-frequency comb that is generated by using an optical parametric oscillator to convert a pair of near-infrared combs into the mid-infrared. The generated combs enable nanosecond-timescale spectroscopy for probing the ultrafast dynamics found in supersonic gas jets, explosions and chemical kinetics.
See Long et al.
