Vibrational polarization beats in femtosecond coherent anti-Stokes Raman spectroscopy: A signature of dissociative pump–dump–pump wave packet dynamics
Knopp et al. @J. Raman Spectrosc. 31, 51 ~2000!# have recently used resonant femtosecond coherent anti-Stokes Raman spectroscopy ~CARS! to prepare and probe highly excited vibrational wave packets on the ground electronic potential surface of molecular iodine. The experiment uses a sequence of three resonant femtosecond pulses with two independently variable time delays. The first two pulses ac...
متن کاملAngular encoding in attosecond recollision
We describe a general concept of using the spatial information encoded in the time-dependent polarization of high harmonic radiation generated by orthogonally polarized two-color laser fields. The main properties of recolliding electron wave packets driven by such fields are reviewed. It is shown that in addition to the recollision energy the angle of recollision of such wave packets, which is ...
متن کاملCoherent control of electron wave packets in dissociating H + 2
Coherent control of electron localization in the dissociation of a hydrogen molecular ion exposed to an attosecond pulse train and a time-delayed near-infrared laser pulse are studied by solving numerically the time-dependent Schrödinger equation. The attosecond pulses in the train generate a train of electron wave packets in the dissociating molecular ion, which are steered by the near-infrare...
متن کاملRotational sideband generation of femtosecond laser pulses via delayed four-wave Raman mixing in hydrogen
We present the efficient frequency conversion of sub-100-fs visible laser pulses by delayed four-wave Raman mixing. Control of intensity distribution and polarization of rotational Raman sidebands is demonstrated by changing the polarization of pump and probe laser pulses. The mechanism of the rotational Raman sideband generation is investigated. It can be explained by angular momentum conserva...
متن کاملInfluence of Heterogeneity on Rayleigh Wave Propagation in an Incompressible Medium Bonded Between Two Half-Spaces
The present investigation deals with the propagation of Rayleigh wave in an incompressible medium bonded between two half-spaces. Variation in elastic parameters of the layer is taken linear form. The solution for layer and half-space are obtained analytically. Frequency equation for Rayleigh waves has been obtained. It is observed that the heterogeneity and width of the incompressible medium h...
