ABSTRACT:
A solid-state laser processing apparatus includes a solid-state laser oscillator, a laser beam diameter controller, an optical fiber, and a processing head. The solid-state laser oscillator oscillates a laser beam. The laser beam diameter controller controls a beam diameter of the laser beam, and includes an aperture. The aperture controls a beam quality of the laser beam defined by M2so as to fall in a range of 85≦M2≦105. The optical fiber guides the controlled laser beam therein. The processing head includes a transfer optical system, and irradiates the guided laser beam to a surface of a workpiece to be processed by way of the transfer optical system.
