A NITROGEN LASER-EXCITED BY A NANOSECOND MICROWAVE-DISCHARGE

Experimental results on excitation of a nitrogen laser by means of a nanosecond microwave discharge in a wave beam are presented. The possibility of producing an atmosphere laser with remote microwave pumping is demonstrated. The numerical model for the nitrogen laser excited by a nanosecond discharge in a cylindrical TE wave in a tube and in free space is constructed. It is shown that, by changing the pressure of the laser mixture, the diameter of the gas discharge tube and the value of incident microwave power one can efficiently control the discharge parameters and achieve total absorption of microwave radiation and high efficiency of laser generation.
