  • Abstract
    A two color far-infrared (FIR) laser interferometer and polarimeter using 5.2- and 6.3-THz CH3OD lasers pumped by a 9R(8) CO2 laser has been developed for future plasma diagnostics. The pump 9R(8) CO2 laser has been stabilized by an external Stark-cell modulation. The performances are the power stability of 108 ± 0.6 W/hour and the frequency stability of ± 230 kHzp-p/hour at the line center.
