Abstract
The present invention relates to a laser apparatus having a structure for removing a skirt portion contained in pulsed light, and a laser processing method using the laser apparatus. The laser apparatus comprises a MOPA fiber laser light source which outputs pulsed light having a skirt portion with a light intensity lower than a predetermined value, and a saturable absorber which removes a skirt portion from the pulsed light outputted from the MOPA fiber laser light source.
