摘要

摘要开发了一种通用技术，用于探测照射固体目标的相对论和亚相对论激光脉冲产生的高次谐波。分析了参数中红外激光系统和基于啁啾脉冲放大的近红外激光系统产生的谐波光谱的特征。实验记录了波长范围在 35 nm 以下的谐波光谱。它们可用作极紫外区的相干辐射源。

Generation and Registration of High Harmonics at Surface Plasma in Coherent Wake Emission and Relativistic Oscillating Mirror Modes by High-Power Laser Pulses

A universal technique is developed for the detection of high harmonics generated by relativistic and subrelativistic laser pulses irradiating a solid target. Features in the spectra of harmonics generated by a parametric mid-IR laser system and near-IR laser system based on chirped pulse amplification were analyzed. Experimental spectra of harmonics in the range up to 35 nm were recorded. They can be used as a source of coherent radiation in the extreme UV region.
