Abstract
A laser oscillator includes a plurality of laser modules, beam coupler () that couples a plurality of laser beams (LBto LB) emitted from the plurality of laser modules to form a coupled laser beam, beam coupler () emitting the coupled laser beam, and a condensing lens unit having a condensing lens, the condensing lens unit condensing the coupled laser beam to have a given beam diameter and guiding the condensed coupled laser beam to a transmission fiber. Beam coupler () has optical members (OCto OC) configured to change optical paths of laser beams (LBto LB). By changing the optical paths of laser beams (LBto LB) by optical members (OCto OC,) a beam profile of the coupled laser beam emitted from the transmission fiber is changed without adjusting a position of the condensing lens.
