【 摘 要 】

The article provides an overview of methods for plasma diagnostics based on the laser interferometry with quadrature recording of informative signals. Quadrature interferometers allow providing a wide dynamic range for measurements of electron densities while maintaining the homogeneous differential sensitivity. The existing range of linear electron density measuring with quadrature interferometers in pulsed plasma installations equals to 1010-1019cm2.
