摘要：
We used the Z-scan technique for measuring the nonlinear refractive index n(2) of a thin composite film formed by copper nanoparticles embedded in silica glass. By varying the number of pulses of the laser shot, we evidenced heating effects induced by the laser during measurements. We were able to estimate the nonthermal refractive-index value, n(2) = (3.0+/-0.3) x 10(-12)cm(2)/W. (C) 2001 American Institute of Physics.
