Abstract

Quasi-phase matching of generated harmonics and laser pulses in several types of plasma is reported. Laser-induced ytterbium, bismuth, vanadium, manganese, and gold plasmas demonstrated the potential to generate powerful coherent radiation by enhancing high-order harmonics in various ranges of the extreme ultraviolet spectrum. Femtosecond pulses with wavelengths of 800 nm and 1300 nm make it possible to demonstrate single-color and two-color generation of groups of amplified harmonics, along with the enhanced single harmonics caused by resonance, in multi-jet laser plasma. The 33× gain factor for the 33rd harmonic in the case of 6-jets Bi LIP was obtained. The highest order harmonics from the multi-jet plasmas (53rd order of 800 nm pump in the case of Bi LIP, 51st order of 1300 nm pump in the case of Yb LIP, and 53rd order of 1300 nm pump in the case of Au LIP) were enhanced compared to the case of the extended plasmas.

在V， Bi, Mn， Yb和Au等离子体中产生的高次谐波的准相位匹配

报道了几种等离子体中产生的谐波与激光脉冲的准相位匹配。激光诱导的钇、铋、钒、锰和金等离子体通过增强极紫外光谱各范围内的高次谐波，展示了产生强大相干辐射的潜力。波长为800 nm和1300 nm的飞秒脉冲使得在多射流激光等离子体中产生单色和双色放大谐波群，以及共振引起的单色增强谐波成为可能。得到了6射流Bi LIP情况下33次谐波的33倍增益因子。多射流等离子体（Bi LIP为800 nm泵浦53阶，Yb LIP为1300 nm泵浦51阶，Au LIP为1300 nm泵浦53阶）的最高次谐波比扩展等离子体增强。
