UPDATE: On June 16, 2020 we filed an International Patent Application No.: PCT/US2020/037871

On June 17, 2019 we filed a provisional patent, Application No. 62/862,598, for a “Low Aberration Optical Delay Scanner.”  This delay scanner will allow us to rapidly and robustly obtain fingerprint coherent Raman spectra at 3.5 wavenumber resolution!  The figure is an example spectrum (in black) compared to a spectrum obtained on the same material (carbon disulfide) with a scanner design commonly used for coherent Raman. We get a 10-fold increase in signal-to-noise ratio, and 10-fold better spectral resolution.
