A new type of dye laser which was pumped with N2 lasers and which generated two wavelengths simultaneously with separation in wavelength as much as 170 nm was shown experimentally. The laser cavity consisted of an output mirror, a grating, two dye cells containing different dye solutions, and a liquid prism having a small top angle (5° or 10°). Farther separation in wavelength is achievable when combinations of dyes and a prism of a larger top angle are chosen.
