A novel approach to absorption spectroscopy is presented which achieves, simultaneously, wide spectral coverage and high spectral resolution. The principle of the technique - dubbed multi-mode absorption spectroscopy (MUMAS) - is described, and demonstrations of the principle are reported using two multi-mode sources: diode lasers and micro-cavity solid state lasers. The technique is shown to have potential for the detection of multiple species and multiple parameters using a single laser and a single detector.
