FIELD: laser cutting equipment.
SUBSTANCE: invention is a laser device containing a support drive device, a laser generator, a mirror assembly, a rotating mirror, an oscillating mirror, and a field lens. The laser generator, the mirror assembly, the rotating mirror, the oscillating mirror, and the field mirror are located on the support drive device along the direction of distribution of laser radiation. The rotating mirror consists of upper and lower pyramids. The upper pyramid and the lower pyramid are identical by shape of a truncated pyramid. The upper pyramid and the lower pyramid are coaxially engaged with each other; a smaller end of the upper pyramid completely rests on a small end of the lower pyramid. The rotating mirror and the oscillating mirror are connected to the support drive device with the possibility of rotation. The support drive device includes the first drive unit for actuation of the rotating mirror and the second drive unit for actuation of the oscillating mirror.
EFFECT: increase in the efficiency of laser cutting.
