Control of coherent transients using shaped pulses

Abstract

Interaction between a two-level system and a weak chirped pulse leads to oscillations of the excited state amplitude, named coherent transients. Their extreme sensitivity to the pulse shape provides a tool for electric field measurement.

Observation of Coherent Transients in Ultrashort Chirped Excitation of an Undamped Two-Level System

Sébastien Zamith, J. Degert, Sabine Stock +4 more

The effects of coherent excitation of a two-level system with a linearly chirped pulse are studied theoretically and experimentally [in Rb (5s-5p)] in the low field regime. The coherent transients are measured directly on the excited state population on an ultrashort time scale. A sharp step corresponds to the passage through resonance. It is followed by oscillations resulting from interferences between off-resonant and resonant contributions. We finally show the equivalence between this experiment and Fresnel diffraction by a sharp edge.

Realization of a Time-Domain Fresnel Lens with Coherent Control

J. Degert, Wendel Wohlleben, B. Chatel +2 more

Perturbative chirped pulse excitation leads to oscillations of the excited state amplitude. These coherent transients are governed by interferences between resonant and off-resonant contributions. Control mechanisms in both frequency and time domain are used to modify these dynamics. First, by applying a phase step in the spectrum, we manipulate the phase of the oscillations. By direct analogy with Fresnel zone lenses, we then conceive highly phase-amplitude modulated pulse shapes that slice destructive interferences out of the excitation time structure and enhance the final population.

Coherent Control of the Selected Excited State by Two-Color Multipulse Excitation

Kenta Abe, R. Nakamura, Hideki Hashimoto +1 more

The selected excited state is controlled by combination of the first pump pulse generating the target state and the second shaped pump pulse. Coherent vibrations can be induced even in the optically forbidden state.
