Abstract: In this letter, we report the demonstration of terawatt (TW)-scale femtosecond vortex laser pulses based on noncollinear optical parametric chirped-pulse amplification (OPCPA) centered at 800 nm. To the best of our knowledge, this is the first experimental study of amplification for OPCPA-based vortex pulses to achieve a powerful ultrafast (TW-scale) vortex pulse output. In this experiment, a 0.5-mJ broadband chirped vortex pulse was amplified to 47 mJ with a 15-mm-long LiB3O5 crystal. The double-pass grating pair compressor with an efficiency of 65% maintained the beam vortex, and a pulse of width 30.1 fs was obtained, corresponding to a peak power of 1.02 TW. This laser can be used in studies on nonlinear optics and relativistic laser-plasma interactions, compact plasma-based accelerators, and light sources.

Abstract: A wavefront correction near the focus of a Pettawatt laser system is demonstrated. After correction, the Strehl ratio of focus is improved to 0.90, and the focal spot size using the f/4 off-axis parabola is reduced to 6.20 × 6.77 μm2. With full peak power, the peak intensity of 2.46 × 1021 W/cm2 is obtained.
