For those of you who handed-in your abstracts in hard-copy, I have tried to type them exactly as they were printed--sorry for typos.  Please email me with corrections.

Yiying Wu    Sum Frequency Generation -- a powerful tool in surface study.
Because of its surface specificity, SFG has proved himself a powerful tool in surface study. This presentation will introduce its principle and review some of its interesting application.

Cheng Cheng Su    Stimulated Raman Scattering of Femtosecond Laser Pulse.
I investigate stimulated raman scattering in pressurized gases, such as H2, etc.  It excited with 300-fs-duration pulses at 390-nm wavelengthand.  Also, it excited with 0.1 mJ of energy.  I show that SRS-generation threshold and conversion efficiency are due to the transient nature of SRS in femtosecond regime. I determine optimal conditions for efficient generation in the broad spectral range 289-797 nm and show how self-phase modulation and white-light generation limit the ultimate conversion efficiency.

Michael Shumway    Description, Characterization, and Uses of Microspheres.
Microspheres are small (diameter 10-500 microns) cavities with very detailed resonance structures.  Applications for these spheres range from particle physics (trapping single atoms) to laser physics (creating unique lasers).  The advantage to using microshperes are their quality factors which have been measured up to Q~1012. This presentation will analyze microspheres and their important properties as well as discussing the results of several groups which have created impressive laser sources from these cavities.

Poul Bering Petersen    The Ti:Safir oscillator: femtosecond pulse creation and propagation.
The talk will include: the Ti:safir oscillator system, modelocking, pulse
chirping and "unchirping" and the autocorrelator for measuring pulse

Steven Johnson    Lasing Without Inversion
 a short overview of LWI
techniques and perhaps a more detailed example of a specific system.

    The use of ultrashort, high-intensity laser pulses has enabled generation of extreme UV and soft X-rays by means of high harmonic generation (HHG) in noble gases. In solids, XUV and X-rays have been generated as a result of laser-plasma interactions. A potential exists for generation of table-top laser X-ray sources with high spatial and spectral brightness, which can be used to reveal important dynamical and structural information in materials.
    This talk should cover the basic mechanisms and issues concerning X-ray generation in gases and solids and briefly address possible applications of generated X-rays.

Henry Chong:   Ultrashort X-ray Pulse Generation using Lasers and Electron Beams
The desire to probe structural dynamics in materials on a short time-scale following excitation has motivated the development of ultrashort x-ray pulse sources.  Work has been done to generate short pulses of x-rays using right-angle Thomson scattering and work is currently in progress to generate x-ray pulses using periodic magnetic structures at synchrotrons. The physics underlying the operation of both sources will be discussed.

Dave Bacon:    The manipulation of coherent quantum information needed to construct a quantum computer represents an experimental challenge which currently borders on the impossible.  The major obsticle in the construction of a quantum computer is the coupling of the computer to its environment and the subsequent decoherence induced by this coupling.  Recently a procedure has emerged for avoiding this decoherence process by encoded over a "decoherence-free subspace" (DFS).  In this talk, I will introduce a general decoherence-free theory and connect this theory to real world examples.  In particular, I will demonstrate how electromagnetically induced transparency (EIT) is a simple one dimensional DFS and propose an extension of EIT which can lead to a full quantum bit (a two dimensional DFS). Further, I will discuss how the collective damping of a large number of two-level atoms by an electromagnetic field mode which is response for the process of superradiance also leads to a DFS.

Colin McCormick:    Properties of Optical Solitons
I will investigate the properties of optical solitons (solutions of the Korteweg-de Vries equation) including their stability in time and during mutual collisions.  With this mathematical basis I will describe the details of a soliton laser that can be used to generate ultra-short (tens of fs) pulses in the infrared.  If time permits I will also talk about soliton propagation in optical fibers and/or soliton solutions to the non-linear Schroedinger equation.
