The utility model discloses a laser spot shaping device, which comprises a binary optical element for spot shape, an electric translation stage for controlling the movement of the binary optical element and a galileo telescope structure for spot shaping, wherein the binary optical element is fixed on the electric translation stage, and the galileo telescope structure comprises a concave lens and a convex lens, and the convex lens and the concave lens are located on the same center line. The movement of the electric translation stage is controlled to drive the binary optical element to move, so that the binary optical element moves to the position coincident with the center of the galileo telescope structure, and the square light spot is output; By controlling the movement of the electric translation stage, the binary optical element is driven to move out of the position coincident with the center of the galileo telescope structure, so as to realize the output of the circular light spot. Through spot shaping, the input round spot is transformed into square spot for output, so that the output spot of the laser can be switched between round spot and square spot. Realize the output conversion between circular spot and square spot.
