“…The local temperature distribution under the laser impingement spot is described using the Eagar-Tsai model [49] , [50] , which provides modified Gaussian profiles with elongated tails:

where

is the initial temperature,

is the laser power, ρ is the mass density, C is the specific heat, a is the thermal diffusivity, σ is a beam radius distribution parameter, v is the speed of the beam, t is the time, and

are the spatial coordinates.…”
