レーザ増幅システム

Japanese Patent JP4335454

B2

In order to improve a laser amplification system, comprising a solid-state body having a laser-active medium, a pumping radiation source for generating a pumping radiation field which passes through the solid-state body several times, an optical pumping radiation imaging means which is arranged between the pumping radiation source and the solid-state body and focuses a leg of the pumping radiation field entering the solid-state body onto the solid-state body and at least one optical refocusing means which focuses a leg of the pumping radiation field exiting from the solid-state body onto the solid-state body again in the form of a leg entering the solid-state body and different to the outgoing leg, in such a manner that as high a pumping radiation power density as possible can be generated in the solid-state body with as little resources as possible it is suggested that the optical refocusing means reshape the leg exiting from the solid-state body into an intermediately collimated leg and reshape the intermediately collimated leg again into the leg entering the solid-state body again and focused onto it.
