Femtosecond Temporal Phase-Resolved Nonlinear Optical Spectroscopy in Molecules with Lock-in Enabled Phase Tracking
Siddhant Pandey, Francis Walz, Niranjan Shivaram
We describe an experiment to measure the emitted real-time electric field from an ultrafast third-order nonlinear optical interaction in molecules, using a phase-tracked spectral i…
