A laser puncher for punching holes on tipping paper, comprises a panel, a light guiding cylinder, a laser connected with the light guiding cylinder, and a transmission system for driving a piece of tipping paper to move in a curved manner. The laser puncher further includes at least one focusing optical head, at least one driving motor fixed on the panel, and a connecting rod fixedly connected with at least one moving optical cylinder. The moving optical cylinder is associated with the light guiding cylinder that penetrates the panel and is connected with the focusing optical head. The driving motor drives the focusing optical head to reciprocate back and forth via the connecting rod and the moving optical cylinder.
