Abstract :
Fluorescence properties of DCM solution and solid dyes were researched applying femtosecond pulses under linear and nonlinear excitation. The reabsorption was distinct in the solid dyes compared with that in solutions under similar conditions. Nonlinear fluorescence spectra of DCM and rhodamine 590 co-doped tunable laser dyes in ethanol were also researched. The energy transfer of rhodamine 590 to DCM was found to be neglectable in the nonlinear excitation spectra of the co-doped liquid dyes.
