RE.PUBLIC@POLIMI Research Publications at Politecnico di Milano
Re.Public@Polimi, archivio istituzionale dei prodotti della ricerca, è il punto di raccolta, conservazione e disseminazione della produzione scientifica del Politecnico di Milano
E' basato su IRIS, il nuovo sistema di gestione dei dati della ricerca (persone, progetti, pubblicazioni, attività) adottato dall’ateneo
EnglishWe introduce a new scheme for two-dimensional IR spectroscopy in the partially collinear pump-probe geometry. Translating birefringent wedges allow generating phase-locked pump pulses with exceptional phase stability, in a simple and compact setup. A He-Ne tracking scheme permits to scan continuously the acquisition time. For a proof-of-principle demonstration we use lithium niobate, which allows operation up to 5 μm. Exploiting the inherent perpendicular polarizations of the two pump pulses, we also demonstrate signal enhancement and scattering suppression.

| Abstract: | We introduce a new scheme for two-dimensional IR spectroscopy in the partially collinear pump-probe geometry. Translating birefringent wedges allow generating phase-locked pump pulses with exceptional phase stability, in a simple and compact setup. A He-Ne tracking scheme permits to scan continuously the acquisition time. For a proof-of-principle demonstration we use lithium niobate, which allows operation up to 5 μm. Exploiting the inherent perpendicular polarizations of the two pump pulses, we also demonstrate signal enhancement and scattering suppression. |
