Measurement of the electron density of weakly ionized laser media with an electron sensor
The method of measuring the electron density in weakly ionized laser media (napprox. =10/sup 8/-10/sup 11/ cm/sup -3/) with an electrostatic electron sensor is analyzed based on experimental data. Analytic solutions describing electron drift in the field of the sensor are obtained based on a simplified model, and the effect of the polarization of the medium on the measured current is determined. The results of model calculations agree well with the complete numerical solution and the experimental data. Criteria are obtained for the applicability of the method. Recommendations are made for the use of fast pulsed circuits under conditions of weak polarization in the field of the sensor and long, with respect to the drift velocity, ionization times.
