Limitation of high-power optical radiation by organic molecules: I. Substituted pyranes and cyanine dyes

Photophysical processes proceeding in polyatomic organic molecules (pyran derivatives and cyanines) excited by high-power laser radiation at 532 nm are studied. Some properties of their changes depending on the structure, solvent, and excitation conditions are determined. The effect of limitation of...

Description
Summary:Photophysical processes proceeding in polyatomic organic molecules (pyran derivatives and cyanines) excited by high-power laser radiation at 532 nm are studied. Some properties of their changes depending on the structure, solvent, and excitation conditions are determined. The effect of limitation of high-power exciting radiation by the organic molecules is found. The maximum limitation (Kmax = 15.0 at the initial transmission equal to 70 %) was observed for the cyanine derivative and is comparable to this effect for fuUerenes C60, which are widely used as radiation limiters.
