Abstract
In a coaxial type gas-flow laser device in which a laser beam axis, an electric discharge axis and a gas flow axis are coincident, at least one centrifugal blower is employed for circulating a laser gas. Where two centrifugal blowers are employed, they oppose to each other in an axial direction of discharge tubes.
