Cavity-enhanced two-dimensional spectrometer

Frequency combs and optical resonators for recording two-dimensional ultrafast spectroscopy signals with high sensitivity.

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

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

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