摘要

给出了0.14 THz高功率单次脉冲信号的频率和功率的测量方法及实验结果。针对高功率太赫兹脉冲频率高、峰值功率高和脉宽短的特点,实验中采用了截止波导滤波法与谐波混频法相结合的方式准确测定了脉冲信号频率,利用辐射场功率密度积分法获取了辐射脉冲的远场功率分布,并给出了单次脉冲的辐射功率。某实验条件下的测量结果表明,0.14 THz高功率太赫兹脉冲的频率为0.146 3 THz,脉宽约为1.5 ns,功率不小于0.5 MW。

Abstract

The measuring methods and experimental results for the parameters including frequency and power of 0.14 THz high-power terahertz pulse are presented. Characterized by high frequency, high peak power and short pulse duration, the terahertz pulse is experimentally measured in frequency using subharmonic heterodyne method combined with cut-off waveguide method, while the far-field power distribution of the radiation pulse is obtained by integration method of power density in the radiation field, and then the radiation power of the single pulse is presented. The measured results under certain experimental conditions show that the high-power terahertz pulse has a frequency of 0.146 3 THz, a pulse duration of about 1.5 ns, and a power level of not less than 0.5 MW.
