Abstract :
The generation of long Stokes pulses by stimulated Raman scattering, which is made efficient by a short seed pulse at the Stokes frequency, is demonstrated both in experiments and in simulations for pump powers below the threshold power for unseeded scattering. It is observed that a second seed pulse with appropriate phase and intensity can extend, switch-off or briefly interrupt the Stokes pulse
