The present invention relates to a marking system having a correction function using a pulse laser beam. More specifically, a plurality of sensors for measuring a distance between a laser radiation unit and an object to be marked are mounted in a sub-robot comprising an x-stage, a y-stage, and a z-stage to mark while moving along an x-axis, a y-axis, and a z-axis in order to enable the laser radiation unit to correct a difference of the set height for radiation of a laser beam which is generated when the object to be marked is marked. Therefore, the marking system allows a worker to mark a preferred marking on the object to be marked at the same depth and eliminates a defect. |
