Аннотация:This letter aims to experimentally demonstrate the possibility of measuring the temporal
dependencies of the surface temperature of an aluminum film confined by a transparent
dielectric in the range below and above the critical temperature of aluminum (from 2 kK to
14 kK). Such temperatures are achieved under the action of a powerful linearly-polarized
laser pulse of one nanosecond in duration onto the film’s surface. To find the temporal
dependencies of the temperature of the aluminum film the nonlinear reflection coefficient of its
irradiated surface is measured to determine the radiation of a Q-switched Nd:YAG laser at the
fundamental wavelength.
