Semiconductors Probed by Ultrafast Laser Spectroscopy, Volume 1 discusses the use of ultrafast laser spectroscopy in studying fast physics in semiconductors. It reviews progress on the experimental and theoretical understanding of ultrafast events that occur on a picosecond and nanosecond time scale. This volume first explores the relaxation of energy and the momentum of hot carriers and then turns to relaxation of plasmas and phonons. It also discusses the dynamics of excitons, polaritons, and excitonic molecules and reviews transient transport and diffusion of carriers. Scientists, engineers, and graduate students will find this book invaluable.

Semiconductors Probed by Ultrafast Laser Spectroscopy, Volume II discusses the use of ultrafast laser spectroscopy in studying fast physics in semiconductors. It reviews progress on the experimental and theoretical understanding of ultrafast events that occur on a picosecond and nanosecond time scale. This volume discusses electronic relaxation in amorphous semiconductors and the physical mechanisms during and after the interaction of an intense laser pulse with a semiconductor. It also covers the relaxation of carriers in semiconductors; transient optical pulse propagation; and methods of time-resolved spectroscopy. Scientists, engineers, and graduate students will find this book invaluable.

"This work documents an advancement in instrumental and experimental capabilities for the study of ultrafast processes and nonequilibrium structure-property relationships in chemical and material systems. Novel results are presented herein, comprising data obtained from time-resolved femtosecond mid-infrared (mid-IR) and visible pump-probe spectroscopic measurements on aqueous solutions of photoacid proton donors HPTS (pyranine), APTS, curcumin. A two-dimensional mid-IR spectroscopy study is presented of proxy-indicators for hydrogen bonding dynamics in aqueous solutions of various halogen substituted acetates (monitoring carboxylate stretch frequency correlations), as well as Car-Parrinello density functional theory based molecular dynamics simulations on switchable "donor-bridge-acceptor" systems, which serve to elucidate proton transfer (PT) mechanisms in the aqueous phase. In particular, Eigen and Zundel-like transient structures have been identified and are associated with concerted or sequential PT pathways, respectively. To conclude this work, ultrafast dynamics in pulsed-laser deposition grown vanadium dioxide films is examined in the mid-IR regime (3-10 um) for transmission and reflection during the optically induced semiconductor-to-metal phase transition to complement recent structural studies using ultrafast electron diffraction. The results demonstrate a characteristic dielectric response behavior at a threshold pump fluence as well as a probe frequency dependent behavior." --

The Third Binational USA-USSR Symposium titled "Laser Optics of Con densed Matter" was held in Leningrad 1 June - 5 June 1987. This volume con tains the full text of 64 papers presented at (or prepared for) the Symposium in both plenary and poster sessions. This Symposium reestablished the very productive series of "Light Scattering" Binational Symposia which were initi ated in Moscow in 1975. Unfortunately there was an eight-year hiatus follow ing the Second Symposium in New York (1979). This interval, caused by serious chilling of the climate of USA-USSR collaboration, deprived the active scien tists on both sides of the opportunity to meet and interact in the active format of a conference. During this eight year interval there has been very rapid and intense development of scientific activity in the general area of laser optics phe nomena. The development of ultrafast laser sources has permitted rapid advances in time resolved spectroscopy and ultrafast processes; the field of optical bistability and strong nonlinearity became a hot topic; and intense work is now underway to clarify ideas of photon localization. These new dev elopments complement many advances in the study of low dimensional systems such as surfaces, new work on phase transitions, and novel studies of elemen tary excitations such as polariton-excitons in localized environments such as quantum wells and heterojunctions.
