The laser-induced oxidation of 2000 Å thick cadmium films on glass substrates is studied by measuring the time-resolved reflectivity and transmission of a probe beam. Under CW laser irradiation, the thickness of the oxide layer is shown to increase linearly with time. Also, the velocity, v, of the CdO-Cd interface increases with increasing laser power, with a step when the melting point of Cd is attained. At the highest powers studied in this work, v varies as v = voexp(−a/P), with vo = 6100 Ås−1 and a=4.8 W.
