The linear and nonlinear properties of Si thin films upon Si wafers made by the use of laser ablation are presented. The linear absorption of the films clearly showed a peak at 9.8 µm (1020 cm-1), whereas the peak at 9.04 µm (1070 cm-1) from the asymmetric Si—O—Si vibration mode was absent. Raman spectroscopy data show a typical 4-cm-1 downshift with respect to the Si line. The nonlinear measurements were performed with a tunable free-electron laser. The nonlinear absorption at λ=9.2 µm was measured to be approximately 2, 25, and 5 times larger than the nonlinear absorption at λ=9.0 µm,λ=9.4 µm, and λ=9.6 µm, respectively.
