Device for processing materials by laser has a reflector element and a solid body laser rod to receive optical stimulus by making transversal pumping geometry available for a diode laser

摘要

A solid body laser rod receives optical stimulus by making transversal pumping geometry available for a diode laser (17). A reflector element (20) with an inlet opening (E) with a large cross section disperses the structure of the diode laser light and fits between the diode laser and the solid body laser rod. The laser diode is set at a distance (a) from the inlet opening for the reflector element.
