Abstract
A laser processing device includes a laser oscillator, optical fiber (), beam control mechanism (), and a laser light emitting head. The laser oscillator includes first and second laser oscillation units that generate first and second laser light rays (LB) and (LB), respectively. Beam control mechanism () includes optical path changing and holding mechanism () that is disposed between second condenser lens () that condenses second laser light (LB) and dichroic mirror () that multiplexes first and second laser light rays (LB) and (LB) and causes the multiplexed light to be incident on optical fiber (). Beam control mechanism () changes an incident position of second laser light (LB) on optical fiber ().
