Injection seeding for the enhancement of high-order anti-Stokes stimulated Raman scattering.
We have investigated the effects of Stokes and anti-Stokes pulse injection on high-order anti-Stokes Raman scattering for efficient generation of vacuum-ultraviolet radiation. The output energies as well as the spatial profiles of anti-Stokes pulses were much improved by injection. Enhancement factors increased for higher orders of anti-Stokes pulses. The shift of optimum pressure together with the change of profile from a ring to a Gaussian-like shape induced by injection indicates that the enhancement is due to the modification of phase-matching geometry in four-wave Raman mixing for anti-Stokes generation.
