Multi-Channel Selective Femtosecond Coherent Control Based on Symmetry Properties
arXiv:0710.0149 · doi:10.1103/PhysRevLett.100.193002
Abstract
We present and implement a new scheme for extended multi-channel selective femtosecond coherent control based on symmetry properties of the excitation channels. Here, an atomic non-resonant two-photon absorption channel is coherently incorporated in a resonance-mediated (2+1) three-photon absorption channel. By proper pulse shaping, utilizing the invariance of the two-photon absorption to specific phase transformations of the pulse, the three-photon absorption is tuned independently over order-of-magnitude yield range for any possible two-photon absorption yield. Noticeable is a set of two-photon dark pulses inducing widely-tunable three-photon absorption.
