Abstract
Disclosed herein is a processing apparatus using a laser beam, which includes a holder for holding a workpiece, and laser beam applicator for irradiating the workpiece, held by the holder, with a pulsed laser beam capable of passing through the workpiece, thereby deteriorating the workpiece. The laser beam applicator includes a pulsed laser beam oscillator and a transmitter/focuser for transmitting and focusing the pulsed laser beam oscillated by the pulsed laser beam oscillator. The transmitter/focuser focuses the pulsed laser beam, with a time difference provided, to at least two focus points that are displaced in the optical axis direction.
