レーザパルスを受ける有限媒質中の非フーリエ温度波伝ぱ

抄録

In this work, using Green's function method, the temperature wave solution predicted by the hyperbolic heat equation is developed for a finite medium exposed to a laser heat flux with an actual temporal profile, whose power has a finite growing and decreasing time. Using the analytical solution, the temperature response and the propagation of the temperature wave due to such heat pulses are investigated for different pulse durations, thicknesses of the medium, and energy absorption depthes. The possibility of exhibiting the temperature wave is discussed for a thin film under a short heat pulse, and the method for measuring the relaxation time is predicted.
