Paper Abstract

Interaction of laser radiation with gold metal film deposited onto the lithium niobate substrate was investigated by means of piezoelectric resonance spectroscopy. Such metal-dielectric heterostructure has eigenmodes which can be excited by application of the probe radiofrequency electric field due to the piezoelectric nature of lithium niobate. Frequencies of these piezoelectric resonances are extremely sensitive to the temperature. During interaction with laser radiation the temperature of the film is determined as a solution of the nonstationary heat conduction equation relying on the experimentally measured induced shifts of piezoelectric resonance frequencies, which were preliminary calibrated in uniform heating conditions.
