The pulse laser with the adjustable annular light spot output according to claim 1, wherein the execution module is configured to print a laser marking pattern, and when the execution module receives a "print instruction", and after a user selects a print preview, the preview module projects a print area onto a surface of a printed surface, and adjusts the brightness of the print area according to the illumination intensity between a laser emitting end and the printed surface; and after the user confirms the print preview, the execution module immediately sends an immediate print instruction to the controller to finish printing the laser marking pattern.
5. The pulse laser with the adjustable annular light spot output according to claim 1, wherein the execution module is configured to cut the cut object, after the execution module receives the "cutting command", the preview module projects a cutting line on the surface of the cut object, and after the user confirms the cutting command in the preview module, the execution module sends the "immediate cutting command" to the controller, so as to directly cut the cut object.
