Abstract
The disintegration yield of the organic dye DODCI dissolved in ethylene glycol and methanol due to cw excitation to the S1-state and due to intense picosecond pulse excitation to higher excited singlet states is determined. In the S1-state DODCI molecules disintegrate after about 5×104 excitation cycles while rhodamine 6G molecules in ethanol survive about 13×106 excitation cycles. In higher excited singlet states the DODCI molecules disintegrate on average after about 10 to 30 excitation cycles, while rhodamine 6G gets destroyed after about 140 excitation cycles.
