PCT No. PCT/EP96/04704 Sec. 371 Date May 4, 1998 Sec. 102(e) Date May 4, 1998 PCT Filed Oct. 30, 1996 PCT Pub. No. WO97/17747 PCT Pub. Date May 15, 1997A laser amplification system with a lasant solid-state material is pumped by pumped light sources and in the case of which one or several pumped beams are guided by mirrors or other optical aids such that each individual pumped beam is focussed several times on different points of the solid-state material, the latter being present in the form of a cohesive or separate solid body which is designed such that the pumped beam is absorbed only in the focal regions, whereby the latter are optically pumped, and in that the laser beam is deflected and guided such that it irradiates all these focal points and is amplified in this manner. This provides a laser amplification system in which the system characteristics are optimized simultaneously, which, in addition, permits a compact construction and is designed such that it is suitable for mass production at reasonable cost.
