Compression of TW class laser pulses in a planar hollow waveguide for applications in strong-field physics
Résumé
We demonstrate pulse post-compression of a TW class chirped pulse amplification laser em-ploying a gas-filled planar hollow waveguide. A waveguide throughput of 80% is achieved for 50 mJ input pulse energy. Good focusability is found and after compression with chirped mirrors a pulse duration of sub-15 fs is measured in the beam center. Whereas a total energy efficiency of ≈70% should be achievable, our post-compressor currently delivers 20 mJ output pulse energy (≈40% efficiency), mostly limited by apertures of chirped mirrors and vacuum windows. The viability of the planar hollow waveguide compres-sion scheme for applications in strong-field physics is demonstrated by generating high-order harmonics in a pulsed Ar gas cell.
