“…The relevant information on the temperature-dependent density, heat capacity, and thermal conductivity is collected from the literature. [22][23][24][25][26][27][28] The boundary conditions of eqn (1) should be satised at both surfaces, i.e., the top surface illuminated by IR lasers and the unilluminated bottom surface. At the top surface (illuminated by IR lasers), the following equation applies:…”
