A device for amplifying high-energy ultrashort light pulses, includes a generator (), a first amplifying/time-stretching element () including a time-stretching element (), a regenerative amplifier (), a multipass amplifier () and a compressor (). The device further includes a second amplifying/time-stretching element (), arranged at the output of the generator (), amplifying and time-stretching the initial light pulses () to generate amplified and time-stretched pulses (), and a filtering element () arranged between the second amplifying/time-stretching element () and the amplification unit (), blocking the low-amplitude light signals () of the amplified and time-stretched pulses ().

Device for amplifying high-energy ultrashort light pulses

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&#x2032;, . . . , M&#x2032;) 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&#x3e;4. The reflective optical elements (M&#x2032;, M&#x2032;, . . . , M&#x2032;) 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.
