| 摘 要： | 本文对不同气压以及入射激光强度下Ne相位匹配高次谐波的光谱蓝移特性进行了实验研究.利用气体盒装置,在谐波平台区域获得最大谐波蓝移为0.13 nm,在谐波截止区获得的最大蓝移为0.07 nm.实验结果表明,通过调节气体盒内气压以及入射激光强度,即改变气体盒中自由电子密度,有利于实现高次谐波光谱蓝移.

| Abstract: | The buleshift properties of high-harmonic generation with phase matching of different filling pressures and laser intensities are experimentally investigated in this paper. The laser buleshift generated in gas cell, with about 0.13 nm in plateau and 0.07 nm in cutoff is obtained. The buleshift is influenced by simply changing the filling pressure and laser intensity, namely, by varying the density of free electrons in gas cell. |
