FIELD: physics.
SUBSTANCE: laser has a gas pumping loop in which there are series-arranged discharge gap formed by two extended electrodes, diffuser, heat exchanger, cross flow fan with an impeller and an extra channel. The inlet opening of the extra channel lies on the pressure side of the fan. The distance between the electrodes is between 0.05 and 0.25 times the external diametre of the impeller. The extra channel is in form of a convergent tube with an outlet hole directed towards the impeller of the fan on the suction side of the fan.
EFFECT: design of a compact TE-type gas laser with efficient laser gas pumping, stable operation and high pulse repetition rate.
