Compressed Sensing of Field-resolved Molecular Fingerprints Beyond the Nyquist Frequency
Kilian Scheffter, Jonathan Will, Claudius Riek +4
Ultrashort time-domain spectroscopy and field-resolved spectroscopy of molecular fingerprints are gold standards for detecting samples' constituents and internal dynamics. However,…

Ultralow-Noise Optical Parametric Amplifier for Stimulated Raman Scattering Imaging
Ines Martin, Yoann Pertot, Olivier Albert +14
We present a 40-MHz ultrafast optical parametric amplifier (OPA), tunable from 0.8 to 1 m, with a relative intensity noise (RIN) matching the shot-noise floor (-160 dB/Hz) above…
