摘要：

In diffusion-cooled gas lasers, the laser medium gas is cooled through the discharge tube wall. Empirical findings suggest that, in longitudinally excited CO(2 )lasers with fast pulsed discharges, the materials of the discharge tube and coolant impact the discharge. This study investigates their effects on fast discharges rather than on cooling. Within a discharge tube with a cooling tube, the discharge tube and coolant create a capacitor, influencing the discharge. The laser output energy varies based on the discharge tube and coolant materials. The primary discharge input energy is influenced by these materials, as is the efficiency of converting it into laser output energy.
