Spectral characteristics of PM-597 and DCM mixture in a commercial laser

We reported the performance of binary mixture—dyes PM-597 and DCM, in a 10-Hz, Nd:YAG-pumped dye-laser system. The mixture-dyes demonstrated broader and more efficient tuning curves compared with those of Rhodamine 590 and DCM. The mixture dyes provide peak conversion efficiencies of 36% at 618 nm. Also by adding SHG, the mixture dyes provide high and stable laser intensity near 308 nm, which used for degenerate four wave mixing (DFWM) studies of OH in combustion diagnostics. This enhanced efficiency should improve the signal-to-noise ratio in multi-spices DFWM measurements with the continuous tuning dye laser.
