Abstract
A laser machining device includes a stationary platform configured for carrying a workpiece, a movable platform opposite to the stationary platform, a laser machining unit and a distance measuring unit both fixed on the movable platform. The laser machining unit machines micro-structures on the workpiece. The distance measuring unit measures a distance between the movable platform and the workpiece, and adjusts the movable platform to make sure a laser beam emitted by the laser machining unit is focused on the workpiece.
