Abstract
Laser heating of semi-infinite solid substance is introduced and analytical solution appropriate to the laser machining power intensities is obtained. Both conduction limited and non-conduction limited cases are considered. The limiting cases in non-conduction limited equation are investigated and the equation governing the conduction limited heating is deduced. In the case of non-conduction limited heating process, the location of maximum temperature and its functional relation with the substance and laser properties are developed. Steady state analysis of the heating process is taken into account and limiting laser power intensity is concluded. In addition, the applicability of Fourier heat conduction equation in laser heating is discussed.
