Abstract :
The aim of this work is to produce mid-infrared picosecond pulses with energies of the order of 1 mJ, tunable in the range of 4-10 μm, at a repetition rate of 10 Hz. An optical parametric chirped-pulse amplification scheme and a longer crystal are used to increase the amplified pulse energy while maintaining a high peak-power. Parametric amplification (type-I difference-frequency mixing) in a AgGaS2 crystal is used to increase the energy of micropulses provided by Free Electron Laser for Infrared Experiments (FELIX), while preserving tunability over the 4-10 μm wavelength range.
