Abstract:
1. A pulse laser processing device comprising: a reference clock oscillating circuit which generates a clock signal; a laser oscillator which emits a pulse laser beam synchronized with the clock signal; a laser scanner which scans the pulse laser beam only in a one-dimensional direction in synchronization with the clock signal and produces a scan position signal related to a position of the scanning; a stage on which a target processing material can be placed and which moves in a direction orthogonal to the one-dimensional direction, a movement of the stage being controlled in a direction orthogonal to the one-dimensional direction based on the scan position signal from the laser scanner; and a pulse picker which is provided on an optical path between the laser oscillator and the laser scanner and which switches between passing and blocking the pulse laser beam in synchronization with the clock signal.
