Abstract
The National Ignition Facility at LLNL recently commissioned the first set of four beam lines into the target chamber. This effort, called NIF Early Light, demonstrated the entire laser system architecture from master oscillator through the laser amplifiers and final optics to target and initial X-ray diagnostics. This paper describes the major installation and commissioning steps for one of NIF's 48 beam quads. Using a dedicated single beam line Precision Diagnostic System, performance was explored over the entire power versus energy space up to 6.4 TW/beam for sub-nanosecond pulses and 25 kJ/beam for 23 ns pulses at 1w. NEL also demonstrated frequency converted Nd:Glass laser energies from a single beamline of 11.3 kJ at 2w and 10.4 kJ at 3w.
