Abstract

A laser beam generation device includes power supply units, LD modules, a combiner, and a control device. The LD modules receive currents from the power supply units, and output laser beams. The combiner collects the laser beams and outputs one laser beam. The control device generates control signals such that power of the laser beam becomes a laser output setting value and such that the currents become current command values. Phases of pulses of the control signals are shifted from each other by 60 degrees.
