Abstract
Shifted Excitation Raman Difference Spectroscopy (SERDS) implemented with two wavelength-stabilized laser diodes with fixed wavelength separation is discussed as an effective method for dealing with the effects of fluorescence in Raman spectroscopic analysis. In this presentation we discuss the results of both qualitative and quantitative SERDS analysis of a variety of strongly fluorescing samples, including binary liquid mixtures. This application is enabled by the Volume Bragg Grating® (VBG®) technology, which allows manufacturing of compact low-cost high-power laser sources, suitable for extending the SERDS methodology to portable Raman spectrometers.
