A TE gas laser contains a gas contour with the following elements arranged in succession: a discharge gap formed by two elongated electrodes; a diffuser; a heat exchanger; a cross-flow fan; and an additional converging channel, the inlet opening of which is situated on the discharge side of the fan, while the outlet opening is oriented towards the fan impeller on the intake side of the fan. The proposed technical solution makes it possible to produce a compact TE gas laser with a high pulse repetition rate.

Gas laser

The proposed gas discharge laser comprises extended solid main discharge electrodes, at each of which at least one ultraviolet pre-ionizer is placed, a gas flow area being formed by means of dielectric gas flow guides and the work surfaces of main electrodes and the pre-ionizers being placed outside of the gas flow area for illuminating a space between the main discharge electrodes through a gap defined between the main electrodes and dielectric guides. The proposed invention makes it possible to design a gas discharge laser for a high pulse repetition frequency mode with high-quality laser radiation.
