The Doppler effect is a universal wave phenomenon that has spurred a myriad of
applications. In early manifestations, it was implemented by interference with a reference …

We review the theoretical status of intense laser induced orientation and alignment-a field of
study which lies at the interface of intense laser physics and chemical dynamics and having …

A new and efficient method for orientation echo spectroscopy is presented and realized
experimentally. The excitation scheme utilizes concerted rotational excitations by both …

We demonstrate an efficient algorithm for inverse problems in time-dependent quantum
dynamics based on feedback loops between Hamiltonian parameters and the solutions of …

We present a detailed theoretical and experimental study of the rotation of the plane of
polarization of light traveling through a gas of fast-spinning molecules. This effect is similar …

High spatial resolution on the image plane (intrinsic spatial resolution) has always been a
problem for ultrafast imaging. Single-shot ultrafast imaging methods can achieve high …

We report the experimental observation of molecular unidirectional rotation (UDR) echoes
and analyze their origin and behavior both classically and quantum mechanically. The …

Generalized vector vortex light beams possess spatially variant polarization states, and
higher-order Poincaré spheres represent a powerful analytical tool for analyzing these …

Light beams carrying orbital angular momentum (OAM) have become over the past few
years a subject of widespread interest with unprecedented applications in various fields …

Increasing interest in the fields of high-harmonics generation, laser-induced chemical
reactions, and molecular imaging of gaseous targets demands high molecular “alignment” …
