| 摘 要： | 通过调控激光波形, 理论上可以实现单阶谐波的增强. 随后, 当基频场强度增强时, 单阶谐波增强现象消失. 当控制场强度增强时, 单阶谐波增强倍率增大, 并且在某一特定光强下具有最大的增强值. 理论分析表明, 单阶谐波的增强现象不仅来源于谐波辐射的折叠区域, 并且与多重谐波辐射能量峰的干涉有关.

| Abstract: | Through the laser waveform control, the enhancement of the single-order harmonic can be achieved. Further, when the fundamental laser intensity is increased, the enhancement of the single-order harmonic is disappeared. When the controlling laser intensity is increased, the enhanced ratio of the single-order harmonic can be enhanced and a maximum enhanced value can be found at the specific laser intensity. Theoretical analyses show that the enhancement of single-order harmonic is not only dependent on the folded structure of the harmonic emission process, but also related to the interference from different harmonic emission peaks. |
