<p>PROBLEM TO BE SOLVED: To provide a laser processing system which keeps temperature distribution near the lighting system of laser beam way in a constant condition and makes it possible to perform a continuous and stable laser processing. SOLUTION: This system comprises an emitting unit 1 which generates a laser beam 1 a for the object to be processed, plural lenses 3, 4 and 5 to control a laser beam 1a which are installed in a laser beam line between a laser emitting unit 1 and objects 8 and 9 to be processed, and a ventilating fan 20 installed between No.1 and No.2 movable tables 6 and 7 to hold the objects 8 and 9 and the lens 5 which discharges heat of sodium lamps 14 and 15 to the outside.</p> |
