ABSTRACT
Spatial light modulation based on nonlinear absorption of light by excited-state molecules in C[sub 60]-toluene solution is demonstrated. Amplitude modulation of probe laser beam transmissions at 747 and 885 nm, corresponding to the peak absorption of T[sub 1] and S[sub 1] states, by the modulation laser beam intensity induced population changes at 532 nm has been analyzed using the rate equation approach, for various values of the small-signal absorption coefficient. It is shown that for T[sub 1] and S[sub 1] states, modulation up to 100% and 94.5% can be achieved for a laser beam intensity of 800 W/cm2 and 1 kW/cm2 at 532 nm, respectively. © 2000 American Institute of Physics.
