纳秒级脉冲宽度的 100 焦耳级 Nd: 玻璃激光系统已建成，可作为高通量激光科学实验的标准源。该激光系统的典型脉冲持续时间为 3-5 ns，光束直径为 60 mm，采用一系列连续的棒状放大器，可在 3 ns 的时间内在 1053 nm 处实现 100 J 级的能量。变频可在351 nm处提供50-J级别的能量。除了能量输出的高稳定性之外，该激光系统最有价值的是输出的高时空光束质量，包括均匀的方脉冲波形、均匀的平顶空间注量分布和均匀的平顶波前。
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.
