Abstract
PURPOSE:To process a brittle material with good efficiency by performing concurrently a heat treatment using laser and a processing treatment, e.g., cutting, welding, etc., on a material to be processed. CONSTITUTION:The laser beam 2 emitted from the laser oscillator 1 is split by the beam splitter 4 consisting of a half mirror, and then the laser beam reflected and bent downward vertically by the half mirror is regulated to an energy density suitable for preheating by the lens 8. The laser beam which permeated through the half mirror is bent downward vertically by the beam bender 3 consisting of a total reflection mirror and then focused into a small spot of a high energy density suitable for processing using the lens 7. When a material to be processed is sent in the processing progressive direction 10, preheating and cutting or welding are concurrently conducted. Or, when the processing progressive direction is inversed, a processing- postheating treatment is made possible. The method is applicable to the cutting of brittle materials, e.g., glass, etc., and also to the welding of high-carbon steel materials or the like.
