Mechanisms for the control of two-mode transient stimulated Raman scattering in liquids
Recent adaptive feedback control experiments demonstrated control of transient i.e. nonimpulsive Stokes emission from two closely spaced Raman-active modes in liquid methanol e.g., B. J. Pearson et al., Phys. Rev. A 63, 063412 2001 . Optimally shaped pulses were found that selectively excited one of the two Stokes lines alone, optimized emission from both modes together, or completely suppresse...
متن کاملTransient stimulated Raman scattering in gas mixtures.
We studied, for the first time to our knowledge, transient stimulated Raman scattering in H(2)- D(2) and H(2)- CH(4) gas mixtures excited with 200-fs and 2-ps, 390-nm pulses. Depending on the composition and partial pressure, of those gases, we observed approximately 40 output lines simultaneously. Under optimum conditions a conversion efficiency of as much as 8% in the combination Raman line a...
متن کاملTransition from transient to stationary behavior in stimulated Raman scattering
The transition between the transient and the stationary regimes of stimulated Raman scattering is examined computationally for pulses with a sharp initial rise. We find that the transient-regime predictions are useful for times less than T2 regardless of the pulse duration and that the stationary-regime predictions become useful only for times much greater than T2 . © 1996 Optical Society of Am...
متن کاملIntegrability and Self-Similarity in Transient Stimulated Raman Scattering
The phenomenon of stimulated Raman scattering (SRS) can be described by three coupled PDEs which define the pump electric field, the Stokes electric field, and the material excitation as functions of distance and time. In the transient limit these equations are integrable, i.e., they admit a Lax pair formulation. Here we study this transient limit. The relevant physical problem can be formulate...
متن کاملSideward Stimulated Raman Scattering
The SRS of a short laser pulse is important in the contexts of particle acceleration2 and inertial confinement fusion.3,4 In previous studies of the spatiotemporal evolution of SRS,5–13 the Stokes waves were allowed to pass freely through the pulse boundaries. However, the radial ponderomotive force associated with the pulse can expel plasma from the neighborhood of the pulse axis, in which cas...
