| 摘 要： | 报道了在４５ｆｓ－２ＴＷ激光装置上以Ａｒ惰性气体为介质产生高次谐波的实验结果，实验中通过研究气体密度和激光能量对谐波辐射的影响，找到了适当的气体密度和激光能量范围，并在Ａｒ气中观察到８１次（９．７ｎｍ）的皆波辐射，这时迄今为止，人们在Ａｒ气中所能观测到的最短波长的谐波辐射，经分析表明，高于５７次的谐波是由Ａｒ离子产生的。

| Abstract: | The experimental results of high order harmonic generation in Ar noble gases using an 45 fs, 785 nm Ti:sapphire laser pulse are presented. The effects of gas densities and pulse intensities on harmonic emission are studied, The harmonic generation up to order 81 (9.7 nm) under optimum experimental condition is observed, which is to date the shortest wavelength hormonic emission in Ar noble gases. Analyses show that the harmonics higher than order 57 are generated from Ar +. |
