Ultrafast Phenomena XI

This volume contains papers presented at the Eleventh International Conference on Ultrafast Phenomena held at Garmisch-Partenkirchen, Germany, from July 12 to 17, 1998. The biannual Ultrafast Phenomena Conferences provide a forum for dis­ cussion of the latest advances in ultrafast optics and their applications in science and engineering. The Garmisch conference brought together a multidisciplinary group of 440 participants from 27 countries, including 127 students. The enthu­ siasm of this large number of Participants, the high quality of the papers they presented and the magnificent conference site resulted in a successful and pleasant conference. Progress was reported in the technology of generating ultrashort pulses, in­ cluding new techniques for improving laser-pulse duration, tunability over broad wavelength ranges, output power and peak intensity. Ultrafast spectroscopy con­ tinues to provide new insight into fundamental processes in physics, chemistry, biology, and engineering. In addition to analyzing ultrafast phenomena, control of ultrafast dynamics now represents an important topic. Ultrafast concepts and tech­ niques are being applied in imaging and microscopy, high speed optoelectronics, mat~rial diagnostics and processing, reflecting the maturing of the field. Acknowledgements. Many people contributed to the success of the conference.
