Abstract
A fiber laser beam processing apparatus is configured by a fiber laser oscillator, a laser power source unit, a laser beam injecting unit, a fiber transmission system, a laser beam irradiating unit, a processing table, etc. A portion of a fiber laser beam oscillated and outputted by the fiber laser oscillator is received by a photo diode for monitoring the power through a beam splitter. An output signal of the photo diode is sent to a laser power source unit. The power source unit receives the output signal of the photo diode as a feedback signal and controls a driving current or an excitation current to be supplied to a laser diode of a pumping unit such that the laser output of the fiber laser beam equals a set value.
