Abstract
A gas laser device includes, in succession along an optical axis, a gas laser excited by a travelling wave, a convergent lens, two parallel-sided optical prisms adhering to one another in a symmetrical position in relation to the axis, and another convergent lens. The arrangement is such that two divergent elementary beams produced by the laser are brought together to have substantially less divergence.
