The Si excited-state absorption cross-section spectrum of DODCI in ethylene glycol is determined in the wavelength range from 500 nm to 750 nm. The S-1 state is populated by amplified femtosecond dye laser pulses (wavelength 592 nm) and the S-1-state absorption and emission behaviour is probed with a femtosecond light continuum. A general analysis procedure is developed to extract absolute excited-state absorption cross-sections from the measured transmissions. For DODCI in ethylene glycol the wavelength regions of saturable absorption (mode-locking application), reverse saturable absorption (optical limiter application), and effective stimulated emission (laser application) are determined.
