Fast third-order optical nonlinearities in metal alloy nanocluster composite glass: negative sign of the nonlinear refractive index
The fast component of the nonlinear refractive index, n 2, of a composite film formed by alloy nanoparticles embedded in silica was measured by Z-scan technique, in conditions free from cumulative heating effects. By using a single 6 ps long laser pulse at 1 Hz, 527 nm of wavelength, a negative sign...

| description | The fast component of the nonlinear refractive index,
n
2, of a composite film formed by alloy nanoparticles embedded in silica was measured by
Z-scan technique, in conditions free from cumulative heating effects. By using a single 6
ps long laser pulse at 1
Hz, 527
nm of wavelength, a negative sign of
n
2 was evidenced. An explanation of this result is suggested, based on the dielectric confinement effect. The fast refractive index value, in modulus, is of the order of 10
