报道了在45 fs-2 TW 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(9.7 nm )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 The experimental results on the generation of higher harmonics using Ar inert gas as a medium on a 45 fs-2 TW laser were reported. In the experiment, the influence of gas density and laser energy on the harmonic radiation was studied, the proper gas density and laser energy range were found, and 81 times (9.7 nm) harmonic radiation was observed in Ar gas, The harmonic wave radiation of the shortest wavelength that people can observe in Ar gas is analyzed, it is shown that the harmonics higher than 57 times are generated by Ar ions
