Abstract
A laser machining device machines a machining target subject by irradiating the converged laser beam output from each laser diode of a plurality of laser diodes connected in series to each other. A machining laser beam output-power driving circuit Qoutputs a machining laser beam by driving the plurality of laser diodes-d,. A guide light output-power driving circuit Qoutputs a guide light by driving a partial laser diodeof the plurality of laser diodes. A selection means SW, SWselects the guide light output-power driving circuit on determining the position and selects the machining laser output-power driving circuit on a laser machining. A setup value comparison circuitcontrols the electric current flowing through the part of laser diodes to be below the electric current setup value to output the guide light having electric current not higher than the predetermined value.
