Spectral spreading and control device for high peak power pulse lasers

摘要

The present invention relates to a spectral stretching and control device for high peak power pulse lasers, which does not limit the extraction efficiency of the amplifiers in the CPA chain into which said device can be inserted, and it is characterized in that it comprises an acousto-optical device for dispersing light pulses, which is programmable in terms of spectral amplitude, disposed in a multi-pass amplifier.
