本文利用啁啾波形调控和双色场波形调控对单次谐波光源的产生进行了研究.结果发现:在啁啾波形调控下,单次谐波光源的调节范围在170 次到370 次谐波区间,能量调节范围较宽.并且,单次谐波的产生对激光脉宽和光强的要求不高.在双色场波形调控下,单次谐波光源的调节范围仅在80 次到110 次谐波区间,能量调节范围较窄.并且,单次谐波的产生对激光脉宽和光强的要求较高.
Generation of single harmonic light source by using two kinds of waveform controlling methods
In this paper,the generation of the single harmonic light source is studied by using chirp waveform control and two-color waveform control.The results show that,in the case of the chirp waveform control,the adjustable range of the single harmonic light source is from 170th order to 370th order,and the energy adjustable range is wide.Moreover,the requirement of the single harmonic generation is not the very high to the laser dura-tion and laser intensity.In the case of two-color waveform control,the adjustable range of the single harmonic light source is only from 80th order to 110th order,and the energy adjustable range is narrow.Moreover,the re-quirement of the single harmonic generation is a little bit high to the laser duration and laser intensity.
