    摘要: A method and apparatus for working a workpiece with a laser and a working head designed for movement, even though the length of an optical path from a laser oscillator to a working point (laser head) varies as the working head moves. A condensing optical component, formed of a lens and the like, is inserted in the middle of the optical path, and the condensing optical component is shifted so as to be within a workable region for proper working of a workpiece depending on the length of the optical path from the laser oscillator to the working head during the working. That is, a laser beam can be narrowed by shifting the position of the condensing optical component so that its propagation characteristic corresponds to the varied optical path length. In this arrangement, the amount of shift required of the condensing optical component is so small that a compact laser working machine can be obtained.
