Abstract

A profile selector includes at least one beam-forming lens refracting a laser beam to be incident so as to convert a beam profile and emits a laser beam having a beam profile selected from a plurality of beam profiles. A collimating lens converts a laser beam of a divergent beam to be incident into collimated light. A focusing lens focuses the collimated light emitted from the collimating lens and irradiates the focused beam to a sheet metal of a processing target. A moving mechanism moves the collimating lens along an optical axis such that a deviation of a focal point is reduced caused when the beam profile of the focused beam emitted from the focusing lens is selected by the profile selector.
