We report the design for a high-power optical parametric chirped-pulse amplifier (OPCPA) at 3200 nm central wavelength for the MIR-HE laser at ELI-ALPS, aiming to provide 20 mJ pulse energy and sub-2.5 cycles pulse length.

Ultrafast Phenomena and Nanophotonics XXIV.
Ultrafast dynamics experiments in physics, chemistry and biology, in condensed matter or gas phase require different types of lasers. We present various OPCPAs as a powerful toolbox to deliver femtosecond pulses from the XUV to THz spectral region. A
