Optically-pumped solid-state laser, has optical element in path of pumping radiation within pumping radiation reflector for altering its intensity distribution

摘要

Laser medium (1) is enclosed by a pumping radiation reflector (7) having an opening (8) for entry of the pumping radiation, with at least one optical element (11) between the pumping source, e.g. a diode laser (9) and the laser medium, positioned in the path of the radiation within the pumping radiation reflector. The optical element alters the intensity distribution of part of the pumping radiation supplied directly to the laser medium.
