Abstract

We report the observation of fractional echoes in a double-pulse excited nonlinear system. Unlike standard echoes which appear periodically at delays which are integer multiple of the delay between the two exciting pulses, the fractional echoes appear at rational fractions of this delay. We discuss the mechanism leading to this phenomenon, and provide the first experimental demonstration of fractional echoes by measuring third harmonic generation in a thermal gas of CO2 molecules excited by a pair of femtosecond laser pulses.

3. Visualizing Coherent Molecular Rotation in a Gaseous Medium [1, 2]

Author

Tutunnikov, I., Prost, E., Steinitz, U., Pierre Béjot, Hertz, E., Billard, F., Faucher, O., and Averbukh, I. Sh

Abstract

We present a study of a non-intrusive optical scheme for visualizing the rotational dynamics in an anisotropic molecular gas. The proposed optical method is promising for visualizing the rotations of symmetric- and asymmetric-top molecules.
