towards inertial fusion energy
Presented to: 2012 Annual DOE Laser Safety Workshop
Mike Dunne
Director, Inertial Fusion Energy
Lawrence Livermore National Laboratory This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344

NIF recently exceeded its design goal of
sustainable operations at 1.8MJ / 500TW
• NIF has been steadily increasing
its laser energy and power
• Now operating 24/7 with
exceptional reproducibility and
reliability
• 1.855 MJ, 522 TW achieved in a
NIC-relevant pulse format
• The NIF has intrinsic capability
to continue on this growth path
for several more years
The laser energy and power
available for experiments have
been steadily increasing
March 15, 2012 1.875 MJ 411 TW
July 5, 2012 1.855 MJ 522 TW
Plans are being developed for enhanced NIF performance, via incremental improvements

High repetition rate solid – state laser (25 kW)
Detailed propagation simulation (based on measured NIF
optics aberrations) shows excellent performance
