Abstract:

The dependence of observed energy parameters of a copper vapor laser (CVL) on excitation conditions determining the reliability of the efficient pumping criterion is analyzed experimentally. CVL energy parameters are shown to correspond to the efficient pumping criterion in the case that the process of direct ionization of copper atoms prevails during formation of population inversion. The main factor limiting the CVL frequency-energy characteristics is the dependence of the rate of voltage increase at the active component of impedance of the gas-discharge tube on the concentration of electrons in the active medium. It is concluded that conditions of efficient pumping of the CVL active medium can be realized in two modes.
