Vibrational Interferometry Enables Single-Scan Acquisition of all χ(3) Multi-Dimensional Coherent Spectra
Abstract
We demonstrate a new method for multidimensional coherent spectroscopy of nanostructures. We use a heterodyne technique implemented with a confocal microscope to record the amplitude and phase of all degenerate third-order wave-mixing processes.
