Summary:A pump light assembly (6) for a disc laser (1), comprising: a focusing device, in particular a concave mirror (11), having a reflecting surface (10) for focusing a pump light beam (8) onto a laser-active medium (2), and a deflecting assembly for deflecting the pump light beam (8) between reflecting regions formed on the reflecting surface (10) and disposed in different angular regions about a central axis (12) of the reflecting surface (10). The deflecting device is configured to produce a deflection of the pump light beam (8) 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 (2 f) in the case of telecentric imaging in order to compensate for a beam expansion of the pump light beam (8), caused by aberrations of the focusing device (11), in successive focusings onto the laser-active medium (2). The invention also relates to a disc laser (1) and to a method for pumping a laser-active medium (2).
