Real time observation of heat transfer along laser-irradiated dielectric surfaces

Photodesorption of Na atoms from rough Na surfaces

“…We have treated this problem previously by solving the two-dimensional heat equation for laser irradiation of mica surfaces via extensive two-dimensional numerical simulations using a method of finite differences. 53,58 After inclusion of radiation and finite size effects the numerical results showed quantitative agreement with measurements using a new laser-based technique for the determination of surface temperatures. 58 Here, we use the same theoretical method to obtain values of surface temperature for mica and lithium fluoride substrates after irradiation with pulsed and cw visible lasers of different irradiances.…”

The thermal response of the substrates is determined by the thermal conductivity K and the diffusivity .…”
