Abstract

An optical pumping module for a laser including an amplifying medium forming a bar with a circular base, at least one light source for optical pumping of the amplifying medium, and a reflector that surrounds the amplifying medium to send the light, along several passes, towards the amplifying medium and forming a cylinder with a polygonal base. The light source is placed in front of one edge of this cylinder on the opposite side of this edge from the amplifying medium. The optical pumping module may be particularly applicable to laser cutting and welding.
