Stimulated ultraviolet radiation from a nanosecond microwave discharge excited in the field of a cylindrical TE wave

The results are given of a numerical calculation of the parameters of spontaneous and stimulated radiation emitted by a nanosecond microwave discharge in nitrogen excited in the field of a cylindrical TE wave in a tube and in free space. An analysis is made of the self-matched dynamics of a microwave discharge and of electronic states of nitrogen molecules, which govern both the emission of radiation from a discharge plasma and lasing. The calculated and experimental results are compared.
