Abstract

PURPOSE:To provide an axial gas laser apparatus having a working accuracy equivalent or superior to that of a transverse laser apparatus, by adapting the apparatus such that laser gas travels between electrodes in two milliseconds or less. CONSTITUTION:In an axial gas laser apparatus comprising a discharge tube 1 having at least a pair of electrodes 2 and 3, a circulating blower 4 for feeding laser gas into the discharge tube and a pair of laser oscillating mirrors 6 and 7 provided at the opposite ends of the discharge tube, the laser gas travels between the discharge electrodes 2 and 3 in two milliseconds or less. Thereby, ripple of light can be decreased to 10% or less and the axial gas laser apparatus is allowed to have a working accuracy improved substantially.
