Paper Abstract

We demonstrate a high repetition rate (3 MHz) Mid-IR supercontinuum (SC) source spanning whose spectrum spanning 1000-4200 nm using a cascade of different nonlinear fibers. Multi-tone absorption spectroscopy measurements are subsequently carried out using this source and a scanning spectrometer probing various concentrations and a combination of different analytes. We further explore a novel algorithm for rearranging the absorption in the IR-region and the NIR region for three-dimensional modeling. We show this method of analyzing the data is robust, that is being able to predict newly added samples of slightly different nature without having to the recalibrate the model.
