Paper Abstract
An electron-beam controlled discharge (EBCD) supersonic CO-laser operating
at transient conditions of excitation (?dis /?tr~1) has been investigated. Mach
number equaled 3.0. The e-beam current density was 1 mA/cm2 . The discharge has been excited between two electrodes spaced 41 mm. The axis of the main resonator has been shifted from the discharge region centre by 120 mm downstream. Small additions of H2 (1-2%) into CO:N2: Ar gas mixture resulted in
the increase of a specific input energy, but the efficiency has been reduced. Maximum efficiency reached 20 % . The output peak power has been gradually growing with the growth of the gas density,and reached 90 kW ( the gas density being 0.5 Amagat ). Five additional cavities have been placed downstream. The usage of the cavities has allowed us to measure the lifetime of the inverse population in CO:N2: Ar mixtures.
