Abstract: Provided is a method for machining micro-holes in a metal or alloy product which relates to the field of micro-hole machining. The method reduces the duration of ejection of primary plasma and the residuals produced during the ejection of the primary plasma, improves the smoothness of the hole wall of the micro-hole, and increases the depth limit of the micro-hole. Injecting energy by a low-energy pulse laser in two attempts further facilitates the reduction of the diameter of the micro-hole and reduces the possibility of cracks, compared with injection of the same energy by a single high-energy pulse laser. Moreover, a ratio between the diameter of the central ring of the ring spot formed by the focused second laser beam and the diameter of the central ring of the Gaussian spot formed by the focused first laser beam is greater than 1, which can improve the injection efficiency of laser energy.
