Lawrence Livermore National Laboratory

The Jupiter Laser Facility (JLF) is a unique laser user facility for research in High Energy Density science . Its three diverse laser platforms offer researchers a wide range of capabilities to produce and explore states of matter under extreme conditions of high density, pressure and temperature.

Titan is a dual-beam platform with a nanosecond, kJ long-pulse beam and a femtosecond, petawatt short-pulse beam derived from a neodymium-glass laser system. Janus is also based on the same neodymium-glass laser system but configured for operation with two nanosecond, kJ beams. COMET is a neodymium-glass laser system designed for the generation of laboratory X-ray lasers.

On this tour, you will visit the Janus Laser Bay (the heart of the Janus and Titan), and the Janus, COMET and Titan areas where LLNL as well as external scientific users perform hands-on operations of experiments.
