Abstract

This disclosure relates to pumping light systems and methods for using a disc laser. A focusing device with a reflecting surface focuses a pumping light beam onto a laser-active medium. A deflecting system deflects the pumping light beam between reflecting regions formed on the reflecting surface that are arranged in different angle regions around a central axis of the reflecting surface in at least a first annular region and a second annular region. The deflecting systems are configured to perform at least one deflection of the pumping light beam between two reflecting regions of the first annular region and at least one deflection between two reflecting regions of the second annular region.
