Excitation mechanisms responsible for the 615.0hyphen;nm oscillation in a Hehyphen;Hg ion laser

摘要

Selective excitation processes responsible for the lasing of singly ionized mercury at 615.0 nm in a Hehyphen;Hg pulsed discharge have been studied by observing the time variation of the populations of the reactants using the Hook method and the sidehyphen;light method. It is found that in the decaying plasma of a pulsed discharge, the principal process is the Penning reaction, while during the discharge the chargehyphen;transferhyphen;type reaction predominates.
