We demonstrate the quasi-phase-matching of a group of harmonics generated in Ag multi-jet plasma using tunable pulses in the region of 1160 - 1540 nm and their second harmonic emission. The numerical treatment of this effect includes microscopic description of the harmonic generation, propagation of the pump pulse, and the propagation of the generated harmonics. We obtained more than 30-fold growth of harmonics at the conditions of quasi-phase-matching in the region of 35 nm using eight-jet plasma compared with the case of imperforated plasma.
我们展示了在1160 - 1540 nm范围内使用可调谐脉冲在Ag多喷流等离子体中产生的一组谐波的准相位匹配及其二次谐波发射。对这种效应的数值处理包括谐波产生的微观描述、泵浦脉冲的传播以及产生的谐波的传播。与无孔等离子体的情况相比，我们在使用八喷流等离子体的35 nm范围内的准相位匹配条件下获得了超过30倍的谐波增长。
