Field-resolved spectroscopy approaching ultimate detection sensitivity
[post]
2022
unpublished
Electric-field oscillations are now experimentally accessible in the THz-to-PHz frequency range1–11. Their measurement delivers the most comprehensive information content attainable by optical spectroscopy – if performed with high sensitivity. Yet, the trade-off between bandwidth and efficiency associated with the nonlinear mixing necessary for field sampling has so far strongly restricted sensitivity in applications such as field-resolved spectroscopy of molecular vibrations12,13. Here, we
