A high sensitivity multi-channel far infrared laser diagnostics with switchable interferometry and polarimetry operation modes for the advanced neutral beam-driven C-2U field-reversed configuration (FRC) plasmas is described. The interferometer achieved superior resolution of 1 ⇥ 1016 m 2 at >1.5 MHz bandwidth, illustrated by measurement of small amplitude high frequency fluctuations.
