The kinetics of Ar+ laser-induced oxidation of 100 nm thick vanadium films on glass substrates is followed by measuring time-dependent changes in reflected and transmitted intensity of a He-Ne probe beam. The growth rate of the vanadium pentoxide layer υ increases with increasing laser power P as υ =υ0 exp(-a/P). At power densities above kW/cm2 vanadium pentoxide crystallizes from the melt.
