ABSTRACT:
A plurality of different laser oscillators are optically connected through respective first laser beam transmission paths to a corresponding number of machining stations. The first laser beam transmission paths are mutually connected optically through laser beam converters and second laser beam transmission paths and the second laser beam transmission paths may be optically connected through laser beam branching devices to a common laser beam transmission path which is optically connected through laser beam branching devices and third laser beam transmission paths to the machining stations, respectively, so that, by suitably controlling the laser beam converters and the laser beam branching devices, a workpiece in one of the machining stations can be machined in various manner with any or any combination of laser beams generated by the laser oscillators.
