Abstract
Gas-phase molecular spectroscopy is performed with a cw, external-cavity spin-flip Raman laser containing an intracavity absorption cell. Significantly enhanced sensitivity is demonstrated under marginal oscillator conditions obtained by decreasing the laser gain to a level comparable with the absorption loss of the cell. Spectra of nitric oxide and carbonyl sulfide are discussed to illustrate the performance achieved.
