Abstract
A high power solid-state non-regenerative optical amplification system () for amplifying a pulsed optical beam, includes a first optical amplification crystal (C) and a second optical amplification crystal (C) for amplifying the optical beam; optical pumping elements for longitudinal pumping amplification crystals (C, C); reflective optical elements (M', M′, . . . , M′) suitable for reflecting the optical beam so that the optical beam makes a total number of N sequential passes through the amplification crystals (C, C), wherein N is an integer and N>4. The reflective optical elements (M′, M′, . . . , M′) are placed in a configuration suitable for alternatively interleaving the sequential optical beam passes through the 1crystal (C) and through the 2crystal (C). A solid-state laser including the amplification system, and a method for amplifying a pulsed optical beam in a two-crystal multi-pass non-regenerative amplification system are also disclosed.
