We present an approach for both efficient generation and amplification of 4-12??m
pulses by tailoring the phase matching of the nonlinear crystal Zinc Germanium
Phosphide (ZGP) in a narrowband-pumped optical parametric chirped pulse amplifier
(OPCPA) and a broadband-pumped dual-chirped optical parametric amplifier
(DC-OPA), respectively. Preliminary experimental results are obtained for
generating 1.8-4.2??m super broadband spectra, which can be used to seed both the
signal of the OPCPA and the pump of the DC-OPA. The theoretical pump-to-idler
conversion efficiency reaches 27% in the DC-OPA pumped by a chirped broadband
Cr(2+):ZnSe/ZnS laser, enabling the generation of? Terawatt-level 4-12??m pulses
with an available large-aperture ZGP. Furthermore, the 4-12??m idler pulses can
be compressed to sub-cycle pulses by compensating the tailored positive chirp of
the idler pulses using the bulk compressor NaCl, and by indirectly controlling
the higher-order idler phase through tuning the signal (2.4-4.0??m) phase with a
commercially available acousto-optic programmable dispersive filter (AOPDF). A
similar approach is also described for generating high-energy 4-12??m sub-cycle
pulses via OPCPA pumped by a 2??m Ho:YLF laser.
