Abstract

A fast response frequency-modulated interferometric polarimeter was designed and constructed with a single 28 μm H2O laser for high density plasma diagnostics. This newly developed modulation system employs an electro-magnetically driven movable mirror to achieve the modulation frequency beyound 1 MHz for about 100 μs duration. The movable mirror performance is studied experimentally in detail. The determination of the Faraday rotation angle is based on the zero-crossing method for the observed beat signals produced by two kinds of rotating plane-polarized waves. The feasibility of the polarimeter constructed was verified in experiments of a field-reversed thetapinch plasma.
