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.
This paper reports the preliminary research results of higher harmonics experiments on the 45fs-2 TW ultra-short super titanium sapphire laser device established in our laboratory with Ar as the nonlinear working medium.The laser energy and gas The effect of the density on the higher harmonics, the highest harmonics present is the 25th harmonic, the corresponding wavelength is 31.4 nm, and the performance of lasers, piezo valves, spectrometers and signal processing and recording systems are also tested. Coordination with each other.
