<p>PROBLEM TO BE SOLVED: To obtain a laser control device for efficiently shortening a radiation control time without deteriorating radiation accuracy of a light beam. SOLUTION: This device comprises a laser device 1 for ejecting a laser light 2, a light coupling device 3 for dividing the laser light into plural light beams 6 and condensing the beams, plural optical fibers 4 for transmitting the light beams ejected from the light coupling device, plural switches 10 which are inserted into an intermediate part of each optical fiber and optionally open/ close an optical path of the light beam, a bundle fiber 9 for constituting ejection ports of the optical fibers in a given arrangement, and a transfer optical system 7 for radiating the light beams ejected from each ejection port onto a target object 8. In this case, the ejection port of each optical fiber is positioned by the bundle fiber, and the radiation shape of the light beam is formed by the arrangement of the ejection ports. Additionally, the switches for optionally opening/closing the passing of the light beam are installed at the intermediate part of each optical fiber, so that the light beams corresponding to a given code are radiated.</p> |
