Fig. 1. Plasma flow profiles (orange-dashed lines) with the corresponding density profiles (blue-solid lines) of the positive flow gradient used in simulations.

Fig. 2. Reflectivity of autoresonant SBS taken from the Vlasov simulations. The small graph shows the reflectivity and its average value when SBS saturates.

Fig. 3. Reflectivity of SBS in the homogeneous plasma when n_e = 0.1n_c.

Fig. 4. Reflectivity versus polarization rotation frequency when Ω/ω₀ = 0.00002, 0.0001, 0.0004, 0.0008.

Fig. 5. Reflectivity versus the frequency difference by two perpendicular linear polarizations with different frequencies when Ω/ω₀ = 0.0001, 0.0002, 0.0004, 0.0013.
