Coherent effects in laser chemistry

Moshe Shapiro, Paul W. Brumer

Published Apr 1, 1992• 0 citations
Publisher

Abstract

We describe the current status of coherent radiative control, a quantum-interference based approach to controlling molecular processes by the use of coherent radiation. In addition to providing an overview of proposed laboratory scenarios, ongoing experimental studies and recent theoretical developments, we call attention to recent theoretical results on symmetry breaking in achiral systems.

Coherent Radiative Control of Chemical Reactions

Paul W. Brumer

Abstract : We continue research on our approach to the coherent radiative control of molecular processes. Our focus remains, as in the past, on extending the general theory and on theoretically designing laboratory scenarios for displaying control. The latter also entails a significant effort to minimize effects which tend to diminish dephasing, thermal population distributions and partial laser coherence. We have, during the course of this grant period, done several seminal pieces of research which both extend the theory and provide the basis for considerably greater advances in the near future. jg p.8

A perspective on controlling quantum phenomena

HERSCHEL A. RABITZ

Controlling dynamical processes at the atomic and molecular scales with laser radiation has been a long-standing dream. The Faraday Discussion presented a cross section of the current experimental and theoretical advances as well as the challenges for the field. This paper summarizes the current status of controlling quantum dynamics phenomena and provides a perspective on the future.

Laser control of chemical reactions in a thermal environment

Zhidang Chen, Moshe Shapiro, Paul W. Brumer

Coherent radiative control is a quantum-interference based approach to controlling molecular processes by the use of coherent radiation. A method of carrying out such control in the presence of thermal broadening effects and laser jitter is described and applied to the photodissociation of Na2.

Experimental investigations of coherent control

Daniel S. Elliott, Ce Chen, Yi-Yian Yin +3 more

The potential of using interferences between transition amplitudes for the coherent control of photoionization rates and of asymmetric photoelectron angular distributions has been demonstrated previously. Current efforts in our laboratories are directed toward control of photoionization of NO, and on control of photoionization channels in atomic barium. This latter system is, of course, much simpler than a molecular system, and thus may provide better insight into the mechanisms involved. We will discuss our investigations of the effects of nonlinear coupling, absorption, and dispersion of the laser beams on their propagation through dense media, as observed via interference effects. Laser band structure effects and the effect of Doppler broadening will also be discussed.

Coherent control of molecular dynamics

Moshe Shapiro, Paul W. Brumer

We review the principles and some recent advances in the theory of coherent control of molecular processes and discuss some of its experimental realizations. Amongst the topics discussed are: bichromatic and pump-dump control; the interference between N-photons and M-photon processes; the optical conversion of a mixture of left- and right-handed chiral molecules into an ensemble containing molecules of the handedness of choice; control of collisional processes; control over chaotic dynamics; effects of decoherence; the solution of the non-degenerate quantum control problem; and control over spontaneous emission and other decay processes.

Development of ultrahigh-precision coherent control and its applications

Kenji Ohmori

Coherent control is based on optical manipulation of the amplitudes and phases of wave functions. It is expected to be a key technique to develop novel quantum technologies such as bond-selective chemistry and quantum computing, and to better understand the quantum worldview founded on wave-particle duality. We have developed high-precision coherent control by imprinting optical amplitudes and phases of ultrashort laser pulses on the quantum amplitudes and phases of molecular wave functions. The history and perspective of coherent control and our recent achievements are described.
