    Abstract

    A 100-J-level Nd:glass laser system in nanosecond-scale pulse width has been constructed to perform as a standard source of high-fluence-laser science experiments. The laser system, operating with typical pulse durations of 3–5 ns and beam diameter 60 mm, employs a sequence of successive rod amplifiers to achieve 100-J-level energy at 1053 nm at 3 ns. The frequency conversion can provide energy of 50-J level at 351 nm. In addition to the high stability of the energy output, the most valuable of the laser system is the high spatiotemporal beam quality of the output, which contains the uniform square pulse waveform, the uniform flat-top spatial fluence distribution and the uniform flat-top wavefront.

    1 Introduction

    High-power laser system plays an important role in many fields, such as inertial confinement fusion (ICF)[1], industrial processing, optical information processing, clinical application of laser medicine and scientific research[2, 3]. On large laser systems[414], there is an ongoing effort to continuously improve various aspects of system performance. Some new problems appear in the process of development of the large solid-state laser system, such as laser-induced optics damage[1519], nonlinear effects after long-range transport of the laser[20, 21] and self-focussing in high-energy Nd:glass laser[22]. In order to study these problems, relatively medium-scale solid-state laser systems are needed to set up for physics experiments, which have the similar fluence to the huge laser system, and operate more flexibly with high spatiotemporal beam quality.
