Abstract

PURPOSE:To uniformalize the temperature of irradiated parts and expand the range of irradiation by converting a laser beam to a laser beam of a hollow cylindrical shape by a converting device, irradiating this to a cylindrical concave mirror and converging the same to a linear shape. CONSTITUTION:The laser beam 12 emitted from a CO2 laser 11 is of a circular shape in section and its energy density is of a Gauss distribution type. When this laser beam 12 is introduced through a circular hole 13a into a converting device 13, it is converted to a laser beam 12a of a hollow cylindrical shape when emitted. This laser beam 12a is led to a cylidrical concave mirror 15, and when it is reflected thereby, it is converted to a linear shape of uniform energy density in the focus position. If the material 16 to be hardened is moved in such a manner that its surface positions at the focus of the cylindrical concave mirror 5, it is uniformly hardened.
