Ultra-stable diode-pumped Nd-doped glass regenerative amplifier for the National Ignition Facility (NIF)

Abstract

Summary form only given. In this paper we describe the current design and performance of a long-pulse regenerative laser amplifier for fusion reactor ignition that uses two, diode-array, end-pumped Nd-doped glass laser amplifiers to achieve the desired performance. The regenerative amplifier is a folded linear arrangement. The 4.5-m-long cavity has a 2-m lens and mode-limiting aperture positioned near the midpoint.
