The influences of seed on stimulated Brillouin scattering pulse shape fidelity in seeded single-cell

To seed a Stokes pulse into the stimulated Brillouin seattering(SBS) generator, the induced SBS by this seeded Stokes pulse can make the SBS threshold reduced, and the best shape fidelity can be obtained. The influences of seed power on SBS pulse-shape fidelity in a seeded single-cell are investigated in theory and experiment.
