Abstract:
A laser processing system comprising:a lens for converging or diverging a laser light and applying the laser light to a surface of an object to be processed;a lens support mechanism for supporting said lens and adjusting a height of said lens from the surface of the object in accordance with an external control signal, said lens having a front surface which faces the object;a height sensor for detecting the height of said lens from the surface of the object;control means for receiving an output signal from said height sensor and controlling said lens support mechanism so as to make constant the height of said lens from the surface of the object;a fist deflector disposed in an optical path of the laser light to be incident upon said lens, for moving a radiation position of the laser light along a first direction on the surface of the object, by changing a transmission direction of the laser light; anda nozzle arranged to let out gas in a direction toward the front surface of said lens which faces the object.
