Abstract :
The nonlinear optical properties of a series of novel boron dipyrromethene derivatives (BODIPY) are investigated by means of the Z-scan technique under 4 ns and 35 ps, visible and infrared laser pulses. All studied BODIPYs were found to exhibit strong saturable absorption and insignificant nonlinear refraction under visible excitation, while no response was observed under infrared laser excitation. The nonlinear optical parameters of the BODIPYs have been determined, revealing large nonlinear absorption coefficient ß values.
