Fig. 1. Percentage of the pump energy transferred to the seed as a function of the seed delay time. 1D simulations are labeled by line-point, 2D by blue circles, and 3D by red squares. At t_p − t_s = 0 ps, the peak power of the seed and pump arrive at the maximum electron density at the same time.

Fig. 2. 2D and 3D simulations: Energy transfer vs incident seed intensity.

Fig. 3. The basic scheme using a plasma as a wave plate based on the phase evolution during the sc-SBS amplification.

Fig. 4. The amplitudes and phases of the pump and the seed at different times. Both the amplitudes of the pump and the seed are normalized to the amplitude of the pump. The phases are normalized to π. The plasma density is constant in the simulation box.

Fig. 5. The amplitudes and phases of the pump and the seed at different times. All the parameters are identical to Fig. 4 except that Gaussian pulses are used here.
