氩气中高次谐波辐射的研究
High-Order Harmonic Generation in Ar Noble Gase
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)的谐波辐射,这是迄今为止,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 +.
