Program Director
Advanced Photon Technologies
NIF & Photon Science

Dr. Constantin L. Haefner is the Program Director for Advanced Photon Technologies in the NIF & Photon Science Directorate. Key program elements are the research and development of advanced short-pulse laser technology, high-average-power and high-peak-power laser systems in support of national security missions, and scientific and industrial applications.

Dr. Haefner has more than 15 years of experience in developing and delivering energetic solid-state, ultrashort-pulse laser systems for laboratory high energy density (HED) physics research. At present, he serves as project manager and principal investigator for the High Repetition Rate Advanced Petawatt Laser System (HAPLS), under construction at LLNL for delivery to the European Extreme Light Infrastructure Facility in the Czech Republic. HAPLS will be the world’s highest average power petawatt laser system, capable of delivering energetic femtosecond laser pulses with 1015 watts of peak power at 10-Hz repetition rate.

Dr. Haefner joined LLNL in 2006 and focused his research on developing state-of-the-art short-pulse laser systems and technologies for the NIF & Photon Science directorate. He has been chief scientist for the Advanced Radiographic Capability (ARC) multi-kilojoule laser system and developed the technologies for several ARC subsystems.

Before joining LLNL, he was chief laser scientist at the Nevada Terawatt, Reno, NV, where he led the design and development of high-energy multi-terawatt laser systems for HED physics research.

Dr. Haefner received his diploma in physics in 1999 from the University of Constance, Germany, and his Ph.D. in laser physics in 2003 from the University of Heidelberg, Germany.
