    Schematic of fast-extending plasma-grating compression (FEPGC) amplification scheme.
    10-μm infrared pulse (red), ionizing pulse (green), and reflected pulse (blue) at t = 33, 42, 51, and 60 ps. The gas density is 0.02 ± 0.01ncr.
    Peak intensity and FWHM duration of reflected pulse with different simulation times. Solid lines: I0 = 3 × 1013 W/cm2 and Δ = 50%; dashed lines: I0 = 2 × 1013 W/cm2 and Δ = 50%; dotted lines: I0 = 3 × 1013 W/cm2 and Δ = 40%; dash-dotted lines: I0 = 3 × 1013 W/cm2 and Δ = 60%.
    Peak intensity and duration of reflected pulse at t = 60 ps with different grating periods.
    Spectrum of reflected pulse at t = 60 ps.
    Gas density and plasma density at (a) and (b) t = 13.33 ps and (c) and (d) t = 35.56 ps.
    Iy at (a) t = 45 ps and (b) t = 49 ps.
