A simple and reliable dye laser emitting two 5-pm lines alternately in successive pulses in collinear beams is described. The proposed laser schemes use a reflecting interference wedge (RIW) as the spectral selector. The two emitted wavelengths produced with the same polarization are determined by 2 orders of the RIW and show high spectral purity and stability. Applications to DIAL measurements for SO2and NO2 are discussed.
