| Popis: | We demonstrate the fabrication and nonlinear optical (NLO) characterization of chalcogenide glass thin films obtained from the solution phase driven approach. The characterization of the films was ahieved using FESEM, AFM, micro-Raman, FTIR, UV-Visible spectroscopy, optical profilometry and XRD. The NLO studies were performed on the solution driven and thermally deposited As2S3 films with [Formula: see text]2[Formula: see text]ps, 800[Formula: see text]nm laser pulses using the Z-scan technique. The results obtained from AFM measurements demonstrated that the surface roughness of the film was considerably low ([Formula: see text]2[Formula: see text]nm) and Z-scan data indicated that the nonlinear refractive index was in the 1.0–[Formula: see text][Formula: see text]m2/W range. |
