laser diagnostics, and ultrafast, ultraprecise material diagnostics. A better understanding of the existing ultrashort pulse laser technology will determine their utility for military and industrial applications. 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 third 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.

This workshop was held immediately after the 19-21 September 2005 Boulder Damage Symposium, an SPIE event.
