A Mach-Zehnder interferometer with pulsed nitrogen laser used for electronic density studies in the plasma focus device is described. The light pulse duration of 2 ns enables interferometric measurements to be made at any instant during the plasma evolution in a 20 kJ (20 kV) device. A numerical method for interferogram processing and computation of the electronic density is presented. Some preliminary plasma studies are discussed.
