Investigations of nonlinear optical parameters of C-60 and C-70 films and s
olutions by Z-scan method are presented. Nonlinear refractive indices on th
e wavelength of Nd:YAG laser radiation (lambda = 1064 nm) have been measure
d. Two-photon absorption and nonlinear susceptibilities of fullerene-doped
films and solutions have been studied. (C) 2000 Published by Elsevier Scien
