A beam divergence of the excimer XeCl laser is investigated. Directional patterns of radiation for different unstable resonators have been measured in the far-field zone. The influence of the gas mixture circulation velocity and the pulse repetition frequency on the XeCl-laser beam divergence has been investigated
