Fundamental studies in physics and chemistry include spectroscopy of gas-phase atoms and molecules, developing essential components of quantum mechanics.


This invention is a method to perform passively amplified 2D spectroscopy experiments, and a frequency comb and optical cavities approach was implemented. Implementation is created through coupling multiple frequency combs to higher-order cavity modes, background-free, cavity-enhanced 2D spectroscopy signals are naturally generated via phase cycling. Cavity-enhanced ultrafast transient absorption spectroscopy, the signal to noise is enhanced by a factor proportional to the cavity nesse squared.


The sensitivity will be probably 3-4 orders of magnitude higher than conventional 2D spectrometers and it can use a lower peak power laser which is less expensive.
