Its intent was to bring together an international and interdisciplinary group of scientists to discuss recent progress, pertinent problems, and open questions in the field of coherent control in atoms, molecules, and semiconductors, in particular. Twenty-seven scientists from the physical chemistry, quantum optics, semiconductor, electrical engineering, and laser communities accepted our invitation and made this event a meeting of exciting presentations and vivid discussions. This volume contains the proceedings of this workshop. Most speakers accepted our invitation to provide a manuscript either on specific aspects of their work or a brief review of their area of research. All manuscripts were reviewed. It is hoped that they provide not merely an overview of most of the issues covered during the workshop, but also represent an account of the current state of coherent control in general. Hence, it is hoped that they are also of interest to a large number of scientists active in one of the areas listed above. The organizers of this workshop would like to thank all the participants for making this meeting a complete success. We are particularly indebted to Dr. Larry R. Cooper at the U.S. Office of Naval Research and Dr. Michael A. Stroscio at the U.S. Army Research Office for external financial support. We also wish to thank the Vice-Chancellor's Office for Research, the College of Liberal Arts and Sciences, the Department of Physics at the University of Illinois-':a t Chicago for internal financial support. Finally, we wish to thank Dr. Xuedong Hu, Dr. Manjusha Mehenda~e, Tatiana Krivocheeva, and Nathan W. Rimington for help with the organization of this workshop. Walter Potz, Chair W.

Coherent control of molecular processes provides a means of controlling the dynamics of molecules, and of molecular processes, via'laser induced quantum interference. We briefly review this approach, with a fo cus on scenarios useful for controlled currents in semiconductors and on alternate new control scenarios. 1. Introduction Since 1986, efforts to control molecular motion and molecular processes have turned to the use of quantum interference as a means of directing molecules towards desired goals. Below we provide a brief sketch of the ideas which underlay the coherent control approach and call attention to the two scenarios which have either been proposed or utilized to control photocurrents in semiconductors. In addition we mention recent new di rections in this area. Both comprehensive (Shapiro & Brumer 1997) and elementary reviews (Brumer & Shapiro 1995) are available elsewhere. Al ternate methods of addressing the molecular control problem have also been recently reviewed by Gordon and Rice (1997). Many of the proposed coherent control scenarios rely upon a simple way of achieving active control over the prepared and final state of the system. 3 W. Pötz et al.
