ABSTRACT:
A surface heat-treating apparatus which focuses laser beam onto a surface of a workpiece for heat-treating the same comprises a composite cylindrical segment mirror and a cylindrical mirror provided in a subsequent stage thereof. The composite mirror is made of two cylindrical segment mirrors joined together with a predetermined angle in a V-shaped manner so that the laser beam reflected by the two component cylindrical segment mirrors of the composite mirror is transmitted to the cylindrical mirror in a manner reversed with respect to the lengthwise and widthwise directions of the composite cylindrical segment mirror and a heat-treating area of a rectangular configuration is thereby provided on the workpiece.
