Abstract

I present a study of laser-induced plasmas (LIPs) produced on the surfaces of molecular targets to create optimal conditions for high-order harmonics generation during the propagation of femtosecond pulses through the LIP. The resonance enhancement of a harmonic, two-color pump of plasma, quasi-phase-matching and nanoparticle-induced growth of the harmonic yield are analyzed, which allows for the formation of sources of coherent extreme ultraviolet radiation based on molecular plasma formation.

摘要

我提出了一项关于在分子靶表面产生的激光诱导等离子体（LIP）的研究，以在飞秒脉冲通过 LIP 传播期间产生高阶谐波时创造最佳条件。分析了等离子体双色泵浦的谐共振增强、准相位匹配和纳米颗粒诱导的谐波产率增长，这使得基于分子等离子体形成的相干极紫外辐射源的形成成为可能。
