Abstract
A pump light assembly () for a disc laser (), comprising: a focusing device, in particular a concave mirror (), having a reflecting surface () for focusing a pump light beam () onto a laser-active medium (), and a deflecting assembly for deflecting the pump light beam () between reflecting regions formed on the reflecting surface () and disposed in different angular regions about a central axis () of the reflecting surface (). The deflecting device is configured to produce a deflection of the pump light beam () between in each case two of the reflecting regions with an optical path length (2 f+2 d1; 2 f+2 d2) that is greater than the optical path length (2f) in the case of telecentric imaging in order to compensate for a beam expansion of the pump light beam (), caused by aberrations of the focusing device (), in successive focusings onto the laser-active medium (). The invention also relates to a disc laser () and to a method for pumping a laser-active medium ().
