Influence of discharge circuit reactance on CuBr laser output

Efficiency of energy input into the discharge in lasers on self-terminating transitions in metal vapors, in particular copper bromide lasers, determines the energy and efficiency of lasing. This paper discusses the influence of reactive components of the discharge circuit on output power of copper bromide laser. It is shown that decrease in lasing power caused by increase in the discharge circuit inductance can be partially compensated by the connection of peaking capacitor. At the same time, when the inductance of the discharge circuit is equal or less than self-inductance of the discharge tube, connecting peaking capacitor leads to decreasing of lasing energy.
