Paper Abstract
Giant nonlinear refraction has been experimentally observed in gold island films. The real part of the third-order
nonlinear susceptibility χ(3)(ω;ω,-ω,ω) reaches a value of -8×10-5 esu (λ = 532 nm, τ = 10 ns) and +5×10-7 esu (λ = 800
nm, τ = 85 fs). The mechanism of nonlinearity of the refractive index can be associated with the resonance enhancement
of the factor of the local optical field at the pump wavelength due to the excitation of surface plasmons, as well as with
the contribution of the heating of conduction electrons in an ensemble of metal particles.
