About the Event


The laser peening (LSP) process has been in use since the 1990s to improve the fatigue life of metallic aerospace components by imparting a deep compressive residual stress on a component surface. The widespread adoption of LSP for both DoD and commercial applications has been limited by high costs for capital equipment, process development and part processing.

New advancements in LSP technology driven by the commercial marketplace have resulted in significant cost reduction, improvements in processing capability, and new applications. This Collider Event will discuss these advancements and offer ideas on how the DoD can harness the commercial market investments to the LSP technology area. Topic areas include:

  • Next Generation of LSP processing equipment, based on commercial-off-the-shelf (COTS) laser components, which provides improved reliability, up to 50% processing cost reduction
  • Wider range of equipment sizes, including low-energy systems that enable affordable application of LSP for Additive Manufacturing (AM) component surface treatment or replacement of shot peening for critical components
  • New LSP application components such as fiber optic delivery systems and ultra-compact end effectors that enable unprecedented access for large structures and tight/hidden geometries, while also enabling significantly easier processing of in-situ structures
  • Emerging Digital Engineering tools for LSP that enable virtual process development, fatigue life prediction, and cost optimization, reducing application development time/cost by up to 70%
  • New business models, such as direct sale of equipment for organic capability
