AbstractRecent advances in the laser machining technology have made it possible to fabricate parts and features with high accuracy and precision, using high-powered, short-pulsed, Q-switched lasers. To determine the machining parameters to obtain the desired geometrical quality, an understanding of the relationship between the process parameters and the resulting surface profile is ncessary. In the present study, the surface are combined with the thermal transfer properties of the material to develop a procedure to determine the detailed surface profile of the ablated material. While the basic formalism is of considerably more general applicability, this report is restricted to the response of metals to lasers with pulses in the nanosecond pulse width regime.
