The maximum depth in pulsed Nd: YAG laser machining is one of the critical problems due to the relatively small mean beam power. A theoretical model is established to predict the depth of machining by considering the laser beam intensity distribution and the interaction of the beam with the material. The influence of the focal spot position on the depth of machining is analyzed and experimentally investigated. Moreover, the transverse sectional shape of the machined hole or slot can also be approximately predicted.
