Abstract
In a cross flow type laser device of the type comprising a cylindrical vacuum vessel, guide ducts for defining a laser medium circulating path, a fan for circulating the laser medium through the circulating path, discharge electrodes installed in the vacuum vessel for creating electrode discharge through circulating laser medium and a cooler for cooling the circulating laser medium, the fan is constructed as a cross-flow fan utilizing a portion of the inner wall of the vessel as a rear casing and a portion of the guide ducts as a front casing so that the fan has substantially the same axial length as that of the cylindrical vacuum vessel.
