Abstract

High power laser system plays an important role in the field of inertial confinement fusion (ICF) [1]. On large laser systems, there is an ongoing effort to continuously improve various aspects of system performance. In order to study the problems appearing in the process of development of the large solid-state laser system, relatively small-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. A hundred-J-level Nd:glass laser system in nanosecond-scale pulse-width has been constructed to perform as a standard source of high-energy-density science experiments at National Key Laboratory of Science and Technology on Tunable Laser, Harbin. The laser system can be effectively applied to the high-energy laser physics research. The laser system, operating with typical pulse durations from 0.2 to 100 ns and beam diameter 60 mm, employs a sequence of successively rod amplifiers to achieve energy up to 100 J at 1053 nm (1ω) at 3 ns. The frequency conversion can provide energy of up to 50 J at 351 nm (3ω).
