Filed: 1999-12-27
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive optical system for laser beam emission which easily and annularly scans the laser beam with an inclined angle with respect to a work. SOLUTION: A laser beam emitted from an optical fiber 200 and transformed into a parallel beam by a recollimate lens 112 advances in the direction orthogonal to the surface of a work and enters into a rotating block 130. The laser beam is reflected on a first and a second turning back mirrors 134a and 134b in the rotating block and refracted by a prism 135, thereby inclining the emitted laser beam wit respect to the surface of the work. A machining lens 136 is held by a lens holder 137 in a manner that the lens is movable in the direction perpendicular to the beam axis, the incident laser beam is condensed by the lens, and the surface of the work is irradiated by the laser beam. On the other hand, a driving motor 140 rotates the rotating block via gears 142 and 132. As a result, the laser beam having an inclination with respect to the work is scanned in an annular shape on the work.
