We report a simple add-on for broadband stimulated Raman scattering (SRS) microscopes to enable fast and programmable spectroscopy acquisition. It comprises a conventional dispersive spectrometer layout incorporating a fast digital micromirror device (DMD). The approach is validated by acquiring SRS spectra of standard chemicals. We demonstrate a DMD's advantage in broadband SRS by showing higher signal-to-noise ratio using a multiplexed Hadamard spectral basis and compressive sensing detection. Our results apply to a variety of frequency-domain pump-probe spectroscopy.
