ABSTRACT

In terahertz HCN lasers, with pumping by alternating current with frequency 50 Hz, laser radiation is generated as pulses with repetition frequency of 100 Hz. A radiation pulse shape changes depending on variation of the resonator length within the oscillation zone. Each pulse of laser radiation can be transformed in two separate pulses. Thus, frequency of pulses is, doubled. The explanation of this phenomenon is provided in the paper.
