PROBLEM TO BE SOLVED: To reduce heat damage to a skin caused by the continuous radiation of laser beams by providing a control means for controlling a scanning means to radiate a laser according to the irradiation order of respective spot position determined by an order determining means. SOLUTION: The order of spots for laser irradiation is previously stored in a memory 52 corresponding to the pattern of scanning shape and size and a scanner controller 51 reads a corresponding pattern from the set scanning shape out of the memory 52 through a control part 50 and controls driving of respective driving motors based on this information. In this case, the arrangement of regular order can be determined by arithmetic processing due to the control part 50 or the like based on the distribution information of spot positions found from the scanning shape and size as well. Therefore, the adjacent beam spot positions or scanning lines are not continuously irradiated and sufficient cooling time can be applied to one irradiated spot. |
