Abstract
Polarization-resolved Raman, spectroscopy provides Much more information than. its conventional counterpart. However, it usually either requires a complicated setup with two spectrographs and detectors or two measurements must be performed sequentially. This study presents a simple and straightforward:approach, to recording both polarization components simultaneously with a single spectrograph and detector. The vertically and a horizontally polarized laser beam exiting a Wollaston prism are focused into the sample. with a small Spatial separation. The scattered light from both-beams is imaged onto the slit of an imaging spectrograph as two Spatially separated signals, i.e., the polarized and the depolarized Raman signal. Eventually) both spectra are acquired:, on a-single CCD chip simultaneously. Experimental data of ethanol and dimethyl sulfoxide are shown as proof-of-concept The new method has a number of advantages) for example, laser intensity fluctuations and the polarization dependence of the diffraction grating do not play a role. The proposed approach will be. useful for an,improved structural analysis and it will be the enabling technology for temporally resolved enantioselective Raman (esR) spectroscopy.
