[en] The first phase of the Nike 5 kJ laser has been completed at the Naval Research Laboratory, consisting of the oscillator through the first E-beam amplifier, with 28 multiplexed laser beams. The individual laser components are all highly reliable. This laser subsystem is now undergoing laser tests. The energy through the first E-beam amplifier during preliminary measurements was 180 J; this meets the design requirements. Recent oscillator improvements, optical design studies and tests in the propagation bay all indicate that it should be possible to demonstrate a 2% nonuniformity in the total laser system, with 3000 J on the target. A new automatic alignment system demonstrates that there is no longer any difficulty in rapidly aligning multiple-beam laser systems. In a parallel effort at Los Alamos National Laboratory, the Mercury laser is being constructed to address KrF system engineering tests and advanced KrF technology concepts such as advanced pulse shaping, very broad bandwidth, and high repetition rates.
