A laser beam irradiating unit of a laser processing apparatus includes a laser oscillator, a mirror configured to reflect a laser beam emitted from the laser oscillator and propagate the laser beam to a processing point, a power measuring unit configured to measure power of leakage light of the laser beam transmitted without being reflected by the mirror, and a condensing lens configured to condense the laser beam propagated by the mirror and irradiate a workpiece with the condensed laser beam. The control unit measures the power of the leakage light of the laser beam by the power measuring unit while irradiating the workpiece with the laser beam.

Laser processing apparatus

A laser oscillator support table includes a base, a fixed plate supported over the base with intermediary of a Z-axis direction movement unit, and a Y-axis direction moving plate mounted on the fixed plate, movable orthogonal to an X-axis direction. An optical path direction of the beam emitted from a laser oscillator supported by the laser oscillator support table is defined as the X-axis direction. The laser oscillator support table further includes a rotating plate that is mounted on the Y-axis direction moving plate rotatably around a rotation center pin fixed to the Y-axis direction moving plate and supports the laser oscillator, a Y-axis direction movement unit that moves the Y-axis direction moving plate in the Y-axis direction, and a rotational movement unit that rotates the rotating plate around the rotation center pin in a plane parallel to a plane formed by the X-axis direction and the Y-axis direction.
