Optica Laser Congress and Exhibition

Lloyd Hackel

Curtiss-Wright Corporation, USA

Development and Application of a 100 Watt Average Power SBS Phase-Conjugated Nd:glass Laser System

A Nd:glass laser producing 20 J/pulse at selectable 10 ns to 30 ns pulse duration and 5 Hz repetition rate was developed and used in applications from coherent satellite illumination to very successful laser peening.  

About the Speaker

Dr. Lloyd Hackel is Vice President for Advanced Technologies of Curtiss-Wright’s Metal Improvement Company.  This followed a 28-year career at the Lawrence Livermore National Laboratory (LLNL) where he headed the Program for Laser Science and Technology.  Lloyd received a BS in Applied Mathematics and Engineering Physics from the University of Wisconsin in 1971 and a Masters of Science degree in 1973 and Doctor of Science degree in 1974 from the Massachusetts Institute of Technology (MIT). He is  co-inventor of the laser used  by Curtiss-Wright for commercial laser peening. Lloyd is the author of numerous scientific publications and co-inventor of over 25 US and foreign patents. He won five internationally recognized R&D 100 awards for innovative technology development and was awarded three Federal Laboratory Consortium Awards by the US Department of Energy for excellence in technology transfer to industry. Lloyd has been Chairman of the Visitor Advisory Board for the University of Wisconsin Physics Department.

Lloyd led development of a laser peening process to form the wing skins of the Boeing 747-8 aircraft and most recently to prevent intergranular stress corrosion cracking of spent nuclear fuel canisters for the San Onofre Power Plant. He led the initial engineering development to deploy the technology on a range of military platforms including the T-45, the F-35B and F-35C, the F-22 aircraft. 

More recently Lloyd developed technology to stop intergranular stress corrosion cracking of 5000 series aluminum and reduce corrosion-fatigue and hydrogen embrittlement of steels as well as advances in high temperature corrosion-fatigue enhancement Additive Manufactured (AM) and single crystal superalloys with specific interest in improving gas turbine hot section components for improved reliability and fuel efficiency.
