TWO-STROKE AUTOGENERATOR OF A HIGH-FREQUENCY PUMP UNIT OF A GAS LASER Russian patent published in 2022 - IPC H01S3/97 

FIELD: gas lasers pumping.

SUBSTANCE: invention relates to systems for high-frequency pumping of gas lasers with a transverse discharge, to a push-pull self-oscillator for high-frequency pumping of the active medium of a slit-type gas laser. The gas laser pump autogenerator contains the first arm and the second arm, each of which contains a high-frequency transistor module, a matching circuit, a power input that can be connected to a power source, and a power output that can be connected to one of the electrodes of the symmetrical electrode system of the laser emitter. The first arm is connected to the first feedback circuit, and the second arm is connected to the second feedback circuit, the sources of the transistor modules of the arms are connected to each other, and the drains are connected to the power input and connected through the matching circuit to one of the power outputs. The oscillator contains a bias circuit with the possibility of connecting the gates of the transistor modules of the arms with a bias voltage source and a tuning element with the possibility of setting the operating mode of the first and second arms. One side of the tuning element is connected through the first feedback circuit to the first arm, and the other is connected through the second feedback circuit to the second arm.

EFFECT: invention allows to increase the efficiency and reliability of the oscillator.
