Abstract
Near-degenerative near-collinear phase-match geometry for broadband optical parametric chirped-pulse amplification (OPCPA) at ≈ 780 nm is calculated in comparison with nondegenerate noncollinear phase-match geometry. In an experiment on LBO-I near-degenerate near-collinear OPCPA, high gain with broad gain bandwidth (≈71 nm, FWHM) at ≈ 780 nm is achieved by using an ≈ 390-nm pumping pulse. The stretched broadband chirped signal pulse near 780 nm is amplified to ≈ 412 µJ with a pumping energy of ≈ 15 mJ, and the total gain is <3.7×106, which agrees well with the calculation. For a broadband (covering ≈ 100 nm) chirped signal pulse, the theoretical gain bandwidth has been attained experimentally for the first time.
