Abstract: PROBLEM TO BE SOLVED: To fuse a member to be processed in various conditions by using a laser.SOLUTION: A laser fusing machine for irradiating a member to be processed with a laser beam, and processing the member to be processed includes: a laser output device for outputting a multimode laser beam including at least a TEM00 mode and a TEM10 mode; a guide optical system for guiding the laser beam outputted from the laser output device; an irradiation head for guiding the laser beam outputted from the optical system, and irradiating the member to be processed with the laser beam; and a control device for controlling operation of the laser output device. The control device makes a laser beam be outputted from the laser output device at an output rate at which a peak beam intensity of a laser beam radiated to the member to be processed becomes equal to or over 500 W/mm, when the laser beam outputted from the laser output device is the TEM10 mode.
