New Paper: Polarization-controlled optimal scatter suppression in transient absorption spectroscopy

In a new paper in Scientific Reports, Pavel Malý and Bart van Oort show how to improve signal to noice by reducing unwanted scattering in transient absorption experiments.

Although our group is mainly concentrating on theory, in the person of Pavel Malý, we are (as a research group) entering the realm of experimental spectroscopy. By setting specific polarizations of the pump and probe pulses, combined with a polarizer behind the sample, the method proposed by Pavel Malý and Bart van Oort improves the signal-to-scatter by roughly the factor 5 against a simple experimental setup without the polariser.
