Apparatus and processes for chemical sensing are disclosed. Embodiments of the present invention comprise a laser device producing a broadband spectral output that can interact with a sample, a wavelength dispersive element, and a detector. The width of the broadband spectral output is greater than or approximately equal to the width of a spectral feature of the sample. The wavelength dispersive element can resolve the broadband spectral output after the broadband spectral output has had an interaction with the sample. The detector detects the intensity of the wavelength-resolved broadband spectral output.
