摘要： A laser perforator device is controlled with respect to laser power and duty ratio in a manner so as to produce uniform perforations at a selected pitch in a workpiece, such as, a travelling plastic or metallic web. The speed of the workpiece is detected and is combined with the values for the desired pitch and duty ratio to produce pulses of the correct duration. These pulses control a switch that passes a laser level control signal to the laser that perforates the workpiece. The laser level control signal responds to the speed to provide uniform energy density to the workpiece.
