Power amplifier for high frequency CO/sub 2/-laser stimulation

We give the results of construction of the double-ended power amplifier on the generator tetrodes, which is used for the high frequency CO/sub 2/-laser stimulation. The stimulation power approaches 3 kW in pulse and 500 W in the continuous mode, with the operation frequency of 110 MHz. A special attention is given to the effect of interaction of the active elements of the double-ended amplifier with the reflecting load, and to the choice of their operation mode.
