Discussion Leader: J. C. Murphy (The Johns-Hopkins University)
In a complementary measurement scheme, time resolved infrared radiometry has been well known as a technique for depth resolved thermal characterization, but less so as a tool for depth dependent spectroscopy. A new direction for time and depth resolved spectral analysis based on this technique will be featured in a presentation in the opening session of the conference.

Monday, June 28 9:00 AM - Noon | ULTRAFAST PHENOMENA AND SHORT TIMESCALE LASER INDUCED ULTRASONICS |
Discussion Leader: T. Sawada (The University of Tokyo)
The measurement of thermal and elastic material properties on increasingly short length scales in thin film and nanostructured materials systems is being accomplished using ultrafast detection schemes based on transient gratings and related ultrahigh frequency pump-probe thermal and ultrasonic techniques. The time scales accessed by these techniques continue to open up new applications in semi-conductor process measurement as well as providing insight into a new range of thermal and acoustic transport phenomena in engineering materials systems. Our first session on Monday will feature presentations on fundamental processes occurring on these time scales in solids and liquids, as well as new questions which arise from the real world application of ultra fast photoacoustic measurements on thin films.
