Sažetak

The application of a laser interferometric technique is described for the investigation of electron density behind the reflected shock wave in an electromagnetic, T type shock tube. The tube was filled with the mixture of argon and hydrogen (9 : 1) to the pressure of 1 Torr. The advantages and limitations of the method are discussed. The electron density in plasma (2.11 - 3.57 · 10^17 cm ^-3) was determined simultaneously by the laser inter­ferometry at two different wavelengths and by the measurements of the Stark broadening parameters of Hβ line. Results of these two sets of measurements agree within 4 %.
