Ultrashort Pulse Laser Materials Interaction Workshop
23-24 September 2004 Bolder, Colorado

The Ultrashort Pulse Laser Materials Interaction Workshop provides a forum for the presentation of the state-of-the-art ultrashort pulse laser technology and effects; including laser materials interaction and other laser effects. A better understanding of the existing ultrashort pulse laser technology will determine their utility for applications within the defense industry. Understanding the ultrashort pulse laser materials interaction provides a foundation for determining the applicability of ultrashort pulses for diagnostic, material fabrication, and inspection applications in civilian contexts as well.

The second annual Ultrashort Pulse Laser Materials Interaction Workshop brought

together government, industry, and academic leaders for discussions of basic and applied research and technology efforts and the future of ultrashort lasers for military and other applications. Technical presentations covered a diverse spectrum of interests including DOE and DoD laboratories, industry, and other scientific and engineering institutions.

Primary Topics

1. Aerospace Materials Interactions and New Phenomenology
Materials interaction physics - effects - solid, translucent and innovative materials - materials processing and microprocessing - material inspection and repair - sensor materials interaction

2. High Intensity Particle/Wave Generation
Terawatt generation - absorption/scatter - ISR, AW, HSI, MSI - terahertz generation - intense EMI/X-ray radiation - materials interaction with high intensity particles

3. UPL Laser Safety and Laser Eye Protection
New phenomenology - effects/uses - interaction physics
