Abstract

The nonlinear optical properties of the laser ablated silicon nanoclustered films were measured by Z-scan measurements. Measurements that was carried out with a 10-ns, frequency doubled, Q-switched Nd:YAG laser indicated that β(I₀ = 3×10⁴ W/cm²)≈0. The films showed a large nonlinear diffraction effect and underwent bleaching. To eliminate any nonlinear and to assess the time scales of this phenomena, the nonlinear absorption of laser ablated films were measured at different repetition rates. Combination of lowered repetition rates and ultrashort pulses allowed the access intensities several orders of magnitude higher than that obtained with nanosecond excitation and avoid thermal contributions to the nonlinearity.
