我们展示了通过使用双激光脉冲增强锂等离子体 13.5 nm 的极紫外 (EUV) 发射。单个激光脉冲产生的锂等离子体条件使 EUV 发射远远超出了其最佳值。然而，双激光脉冲的利用增强了 EUV 发射能量，在 20 至 50 ns 的延迟时间下，在测量的立体角中观察到其最大带内 EUV 转换效率 (CE) 为 2%。
We demonstrated enhancement of extreme ultraviolet (EUV) emission at 13.5 nm from a lithium plasma by use of dual laser pulses. A single laser pulse produced a lithium plasma condition for the EUV emission far beyond its optimum. Utilization of dual laser pulses, however, enhanced the EUV emission energy, and its maximum in-band EUV conversion efficiency (CE) in a measured solid angle was observed to be 2% at a delay time between 20 and 50 ns.
