<p>In order to reduce the cross-sectional area of the core of an optical fiber used to transmit laser light, the intensity distribution of the laser light emitted from a laser oscillator (111) is shaped by the optical fiber (115) so as to be virtually uniform. The laser light emitted from the optical fiber (115) is focused by a focus lens (119) and introduced into an optical fiber (120). The laser light entering the optical fiber (120) is transmitted to a processing optical system comprising a collimator lens (121) through an f? lens (126). The present invention can be applied to a laser processing device, for example.</p> |
