The effect of frequency multiplication was investigated for a fundamental-harmonic 0.263-THz kW-level gyrotron, in which a certain fraction of its radiation was observed experimentally at the doubled operating frequency. Accurate measurements of the power of such high-frequency generation were carried out based on cyclotron absorption of radiation in a HgTe/CdHgTe quantum-well heterostructure. The maximum power ratio of the second harmonic to the fundamental one is about 10−4 (an absolute power of 10–15 mW at a frequency of 0.526 THz), which agrees well with the results of simulations within the framework of the self-consistent averaged approach performed to describe the multimode generation in gyrotrons.

次太赫兹回旋管频率倍增效应的研究

研究了基本谐波0.263-THz kW级回旋管的倍频效应,其中在两倍的工作频率下通过实验观察到了一定比例的辐射。基于HgTe / CdHgTe量子阱异质结构中辐射的回旋加速器吸收,对这种高频发电的功率进行了精确测量。二次谐波与基波谐波的最大功率比约为10 -4(在0.526 THz频率下的绝对功率为10-15 mW),这与自洽框架内的仿真结果非常吻合用来描述回旋管中多模产生的平均方法。
