Interference Analysis of Photothermal Generation of Waves in Layered Structures

Abstract

The role of the interference of the optical, thermal, and elastic waves in the case of optical generation of thermal and elastic fields in layered media is described. The one‐dimensional case is considered. The influence of the optical, thermal, elastic, and thermoelastic parameters as well as the thickness of the absorbing layer on the temperature and the amplitude of the ultrasonic waves is emphasized.
