摘要

本研究开发了一种通用技术,用于探测由照射固体目标的相对论和次相对论激光脉冲产生的高次谐波。分析了两种不同产生方法的典型特征:中红外范围的参数产生和近红外范围的啁啾脉冲放大。实验记录了 35 纳米范围内的谐波光谱。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. The characteristic features typical of two different generation methods are analyzed: parametric generation in the mid-IR range and amplification of chirped pulses in the near-IR range. 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.
