Abstract

Harmonic seeded operation of a neon-like titanium plasma-based soft x-ray laser is described. The plasma amplifier is pumped with a variation of the grazing incidence technique involving a fast and localized ionization step. We discuss its effect on gain dynamics by measuring the amplifying factor as a function of the delay between pump pulse and harmonic seed. Two different regimes are pointed out, following the pumping scheme used. For one of them, a delay in the gain generation compared with the pumping laser pulse is observed.

摘要

描述了基于类氖钛等离子体的软X射线激光的谐波种子运转。等离子体放大器采用掠入射技术的一种变体进行泵浦,该技术涉及快速且局部的电离步骤。我们通过测量放大因子作为泵浦脉冲和谐波种子之间延迟的函数,来讨论其对增益动力学 的影响。根据所使用的泵浦方案,指出了两种不同的情况。对于其中一种情况,观察到与泵浦激光脉冲相比,增益产生存在延迟。
