LASER AMPLIFICATION SYSTEM

摘要

The purpose of the present invention is to create a laser amplification system that comprises the following members: a plurality of solid-body volumes comprising a laser-effect medium; a pumping radiation source; and a pumping radiation reflector which allows a branch of the pumping radiation field penetrating into the solid-body volume to cross repeatedly said solid-body volume in the form of an exiting branch so that the entering branch and the exiting branch form a first pumping splice. The system also includes a first pumping-radiation path through which the first pumping splices from the pumping radiation field flow during a first sequence. The individual solid-body volumes are submitted as regularly as possible to the action of the pumping power. This invention also provides that each pumping body volume is crossed by a second pumping splice in which the entering branch and the exiting branch are located on a second plane that is different from the first one. This invention also provides a second pumping-radiation path through which the second splices from the pumping radiation field flow during a second sequence. During this second sequence, the order of the solid-body volumes is modified relative to the first sequence.
