We propose a novel approach to broadband coherent anti-Stokes Raman scattering (B-CARS) based on a femtosecond laser at 1035 nm and 2 MHz repetition rate. These features of the driving laser enable white-light continuum generation in bulk media, employed as broadband Stokes. In this way, we demonstrate state-of-the-art acquisition speed (<1 ms/pixel) with unprecedented sensitivity (≈14.1 mmol/L) when detecting dimethyl-sulfoxide in water, covering the whole fingerprint region. To further enhance the performance of the system, we designed an innovative spectral denoiser based on a convolutional neural network, coupled with a post-processing pipeline to distinguish different chemical species of biological tissues.
