ABSTRACT:
A YAG laser mask marker includes a YAG laser oscillator (1), a first deflector (3X, 3Y) for deflecting a laser beam from the YAG laser oscillator in X and Y directions, a liquid crystal mask (6) for displaying a predetermined pattern to be raster scanned by the laser beam from the first deflector, a second deflector (7X, 7Y) for deflecting in X and Y directions the raster scanned light which has passed through the liquid crystal mask, a work (10) on which the raster scanned light from the second deflector is illuminated to print the pattern on an surface thereof, and a controller (11). The controller stores an entire pattern as dot data, divides the stored entire pattern data into a plurality of block-shaped divided pattern data items, and performs printing on the work by lowering an intensity of laser beam by the Q switch, by selecting one divided pattern data item from the plurality of divided pattern data items together with the address data thereof, by displaying the divided pattern data item on the liquid crystal mask as a divided pattern portion, by moving the first deflector to a raster starting position, by moving the second deflector to a printing area on the work on the basis of the address data, and by pulse oscillating the YAG laser oscillator by the Q switch and thereby raster scanning the divided pattern portion displayed on the liquid crystal mask by the first deflector.
