Abstract
A direct-diode laser oscillatorcan emit laser light to a laser processing headbased on the driving commands received from a system controller, which can control a laser robotincluding the laser processing head. The direct-diode laser oscillatorincludes the following: laser moduleseach including a plurality of laser diodes connected in series or in parallel; a power supply circuitfor driving the laser modulesat a constant current, and a power controllerfor controlling the power supply circuitbased on the driving commands and performing a fault diagnosis of the laser oscillatorbased on which one of a plurality of previously divided regions of a diagnosis map the current and voltage applied to the laser modulesbelong to.
