Frequency comb based four-wave-mixing spectroscopy
Published 11 Apr 2017 in physics.optics | (1704.03384v1)
Abstract: We experimentally demonstrate four-wave-mixing spectroscopy using frequency combs. The experiment uses a geometry where excitation pulses and four-wave-mixing signals generated by a sample co-propagate. We separate them in the radio frequency domain by heterodyne detection with a local oscillator comb that has a different repetition frequency.
