A surface treatment device includes a working platform, a laser source, a focus lens, a detector and a controller. The working platform is provided for supporting a workpiece thereon. The laser source is provided for producing laser beams. The focus lens is arranged between the working platform and the focus lens for focusing the laser beams to a spot for treating the workpiece. The detector is provided for detecting information of the spot and generating a feedback signal corresponding to the detected information. The controller is electrically connected with the laser source, the working platform and the detector and configured for receiving the feedback signal from the detector to control emitting of the laser beams of the laser source and movement of the working platform.
