Abstract

Thin films of Bi were grown by pulsed laser deposition on glass substrates at room temperature. The thickness and roughness of the films were characterized by grazing-incidence x-ray reflectivity, and the complex refractive indices were measured in the range from 1.5 to 4 eV by spectroscopic ellipsometry. We performed Z-scan measurements to study the third-order optical nonlinearity of the films. It was found that the Bi films exhibited an unusually large nonlinear refractive coefficient, nI~1.24×10-1 cm2/kW and nonlinear absorption coefficient, αI~-3.97 cm/W , at low laser intensity, ~60 kW/cm2 . This anomaly is believed to have an origin related to melting of the Bi films at the focus spot by the laser beam.
