Femtosecond coherent Raman system with >75 dB dynamic range for probing vibration modes across 250-2400 cm −1

We report on the design and performance of a time-resolved Coherent Raman spectroscopy system with time resolution of better than 120 fs. The coherent transients can be traced with more than 75 dB dynamic range while accessing and probing Raman active modes across a 250–2400 cm −1 frequency. The sys...

Description
Summary:We report on the design and performance of a time-resolved Coherent Raman spectroscopy system with time resolution of better than 120 fs. The coherent transients can be traced with more than 75 dB dynamic range while accessing and probing Raman active modes across a 250–2400 cm −1 frequency. The system delivers an equivalent spectral resolution of better than 0.1 cm −1 regarding line bandwidth parameters for probed Raman resonances.
