The excitation circuits of a copper vapour laser (CVL) with a partial or to
tal discharge of the storage capacitor were analysed. Based on this analysi
s, the effect of prepulse electron density on the repetition rate-energy ch
aracteristics of a CVL was shown to be minimal when the following condition
s are fulfilled: R > 2(L/C)(1/2) and L/R < tau(c) (for partial-discharge pu
mp schemes; C is the storage capacitor capacity, L is the discharge circuit
inductance, R is the prepulse resistance of the active medium, and tau(c)
is the switch turn-on time) and for a high frequency of free oscillations i
n the discharge circuit of a CVL. The conclusion was drawn that traditional
pump schemes limit the energy capabilities of a CVL. The repetition rate-e
nergy characteristics of a CVL can be improved by resorting to schemes with
a shock or complex excitation circuit or their combination.
