ABSTRACT:
An on-the-fly analog switching method and system for providing a switching time of less than one second between energy levels and laser heads for laser shock peening applications. An analog switch is used with variable resistance devices that produce a switching time of less than one second. One advantage of the present invention is that a switching time of less than one second is provided which provides for an energy and time efficient system. The laser shock peening process is never delayed for switching purposes as the switching occurs during the standard pause between treated linear areas.
