Abstract

Startup scenarios are studied for a high-power microwave ultrashort pulse (USP) generator with passive mode locking and consisting of two coupled helical gyro-TWTs operating in the amplification and nonlinear absorption modes. A startup scenario is proposed for a USP generator with a delay of switching on the absorbing section that allows the stability of generated pulses to be improved with a simultaneous increase in the efficiency of the device.
