A new method for single-wavelength detection (SWD) spectroscopy has been developed with the use of synchronous scanning of an optical parametric oscillator (OPO). With the combination of SWD with spatial and temporal discrimination, a high level of background light rejection is achieved. Results show sufficient ambient room light rejection for obtaining complete gas-phase nonlinear Raman spectra with no detectable signs of interference.
