A NITROGEN LASER-EXCITED BY A NANOSECOND MICROWAVE-DISCHARGE

Experimental results on excitation of a nitrogen laser by means of a n anosecond microwave discharge in a wave beam are presented. The possib ility of producing an atmosphere laser with remote microwave pumping i s 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 th e 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 hig h efficiency of laser generation.
