Abstract
A laser machining apparatus includes: a laser oscillator to emit a laser beam; a focusing lens to irradiate a workpiece with the laser beam; a focus position control mechanism disposed between the laser oscillator and the focusing lens and disposed on the optical path of the laser beam and that controls the divergence angle of the laser beam and the incident diameter of the laser beam incident on the focusing lens; a laser beam deflector to deflect the laser beam before the laser beam is incident on the focusing lens; and an emitting angle control mechanism to control the emitting angle of the laser beam that exits from the focusing lens after being deflected by the laser beam deflector.
