摘要
报道了在本实验室建立的45fs-2 TW级超短超强钛宝石激光装置上.以Ar为非线性工作介质.进行的高次谐波实验的初步研究结果.初步研究了激光能量和气体密度对高次谐波的影响,目前得到的最高次谐波为第25次谐波.相应波长为31.4nm.还检验了激光器、压电气阀、光谱仪以及信号处理和记录系统的工作性能.实现了相互间的协调.
The experimental results of high-order harmonic generation in Ar gas with femtosecond Ti:sapphire laser pulses are presented. The laser system, gas jet, spectrometer and signal processing system are examined. The effects of laser intensity and gas density on the harmonic generation are studied. Harmonic orders with the highest reaching 25 are observed at present, corresponding to a shortest wavelength of 31.3 nm.
