Claim:
1. A laser processing device comprising: a laser source having a laser-emitting end being capable of emitting a laser beam along a first beam path; a beam expansion lens mounted in the first beam path and configured to receive the laser beam; a stationary lens mounted in the first beam path and configured to transmit the laser beam passing from the beam expansion lens; a reflector mounted in the first beam path and configured to reflect the laser beam passing from the stationary lens to a second beam path having an included angle with the first beam path; a focusing lens assembly mounted in the second beam path and configured to receive the laser beam reflected from the reflector to process a workpiece by a focusing point of the laser beam; and a high speed vibration unit located on a moving path of the laser beam and being capable of vibrating periodically along a direction parallel to the moving path of the laser beam such that the focusing point formed by the laser source moves periodically.
