An HCN-laser interferometer has been constructed for the electron density measurement of plasmas. The output power of the HCN laser has been stabilized to be fit for long-term operation. The interferometer is of Michelson-type with a concave mirror as the reflecting mirror so as to reduce the refractive effect due to plasmas. The mean electron density of SPAC-II tokamak plasma (3∿7.5×10^<13>cm^3) was measured by this interferometer. The signal-to-noise ratio was 20,which was mainly determined by the fluctuation of the laser output power. Changes of the phase shift corresponding voltage spikes in the one-turn-loop voltage signal were also observed.
