The large Nd-doped glass laser preamplifier system for the National Ignition Facility (NIF) is comprised of 192 separate beam lines that each produce about 20 kJ of 1.05 micron light. The architecture consists of a central, all-fiber master oscillator system, where the light is generated, shaped, modulated, and distributed to 192 beam lines. Next, 192 preamplifier modules amplifier the tailored pulses from 1 nJ up to 10 J, whereupon they are transported to the large amplifier chains where the laser energy is increased to the 20 kJ level. The preamplifier modules contain a diode-pumped regenerative amplifier (regen), two optical subsystems for spatial beam shaping and smoothing by spectral dispersion (SSD), and a larger four-pass amplifier. In this paper we describe the current design and performance of this high gain preamplifier.
