Piecewise Linear Chirp and Rotational Inhomogeneity in Wavepacket Interferometry

Abstract

The recently developed technique of time-resolved nuclear wavepacket interferometry depends on the capability to prepare sequences of ultrashort light pulses among which there are fixed and actively stabilized optical phase relationships.1,2 The resulting ability to superpose nuclear wavepackets with well defined quantum mechanical phase relationships is likely to find application in nonlinear spectroscopy of condensed phase samples, coherent control schemes for chemical reaction dynamics3 and time-resolved detection of molecular geometric phase evolution.4
