Abstract
Apparatus for treating a metal workpiece includes a laser radiation generator arranged to generate and focus a laser beam onto a workpiece, and a part-spherical mirror so positioned as to refocus onto said workpiece the radiation reflected therefrom. The provision of the mirror increases the percentage of the laser radiation energy absorbed by the workpiece.
