Thermal fields in materials irradiated with CO_2 laser beam

摘要

The present report describes in an analytic form, the thermal field in a layer of a material heated by a CO_2 laser beam moving with a constant speed. The presented description, which is a solution of a power balance of a thermal field includes basic thermal parameters of the heated material varying with temperature as well as variable conditions to absorb the energy of the laser radiation beam by a superficial heat source initiated by the radiation. The heat of structural changes and phase transformations within the area of the initiated thermal field are not considered.
