Inertial Confinement Fusion quarterly report October - December 1998, volume 9, number 1

The injection laser system (ILS), or front end, is the portion of the National Ignition Facility (NIF) where a single pulse is produced, modulated, and shaped, then amplified and multiplexed to feed the 192 main amplifier chains in the NIF. The ILS's three major subsystems are summarized in the overview, then described in detail in their own sections. In many cases, the subsystems have been developed and are in an engineering prototype phase in which we work with outside vendors to produce hardware. We have also connected two of the subsystems, the master oscillator room (MOR) and preamplifier module (PAM) development labs, to perform integrated performance measurements on a combined system
