We study nonlinear absorption in a series of ten polymethine dyes and two squarylium dyes using Z-scan, pump-probe and optical limiting experiments. Both picosecond and nanosecond characterization were performed at 532 nm, while Ž. picosecond measurements were performed using an optical parametric oscillator OPO from 440 to 650 nm. The photophysical(More)
