PURPOSE:To utilize effectively the energy of laser beam for the heat treatment of surface of workpiece by irradiating the surface again with the energy of laser beam which is reflected from the same surface. CONSTITUTION:At first a workpiece 1 is irradiated by laser beam 2. Approximately 90% of the irradiation energy of this laser beam 2 is reflected from the workpiece. The reflected beam 3 impinging a reflecting plate 4 irradiates again another portion of the workpiece 1 for the effective surface treatment of the surface of workpiece 1.
