Аннотация
Optical second- and third-harmonic generations in C 60 film have been studied using a Nd:YAG laser as the fundamental light source. Observed dependences of the generated second- and third-harmonic intensities on the polarization of light and on the angle of incidence are discussed based on the symmetry of the film structure. The relatively large third-order nonlinear response of || χ (3) (-3ω; ω, ω, ω)|| ≃2×10 -10 esu has been observed.
