Laser-induced temperature distributions in finite radial-size optical mirror

Study on the impact of grating absorption on substrate temperature under intense laser irradiation

“…When a Gaussian distribution light beam with a beam radius of a is incident on an optical thin film sample with a radius of b and a thickness of d, according to the heat conduction theory, the temperature distribution within the sample T satisfies the heat conduction equation [11][12][13][14][15] :…”
