| 摘 要： | 报道了在 10 5fs 0 .6TW激光装置上以氪气为介质产生高次谐波的实验结果。实验中主要研究了不同气压、不同激光能量、不同偏振特性对谐波辐射的影响 ,并从理论上进行了分析。结果表明 ,要想得到较强的谐波辐射信号 ,必须有适当的气体密度和激光能量 ;要想得到较高次的谐波辐射信号 ,除了有较高的激光功率密度外 ,还必须具备灵敏度高的探测器。

| Abstract: | In this paper, the experimental results of high-order harmonic generation in Kr using an 105 fs, 795 nm laser system are presented. The effects of gas densities, laser intensity and laser polarization on harmonic emission are mainly studied. At the same time, the results are analysed from theory. The results indicate that proper gas densities and laser intensity are needed in order to get stronger harmonic emission; besides having higher laser intensity, the detector of high sensitivity must be possessed in order to get higher order harmonic generation. |
