Dual-comb coherent Raman spectroscopy with lasers of 1-GHz pulse repetition frequency
Dual-comb coherent Raman spectroscopy with lasers of 1-GHz pulse repetition frequency
We extend the technique of multiplex coherent Raman spectroscopy with two femtosecond mode-locked lasers to oscillators of a pulse repetition frequency of 1 GHz. We demonstrate a spectra of liquids, which span 1100 cm-1 of Raman shifts. At a resolution of 6 cm-1, their measurement time may be as short …
