    The improvements of measuring method and laser performance in the HCN laser heterodyne interferometer system for plasma density measuring are introduced. A Fabry-Perot type output coupler which has optimal reflectance and trans-mittance is used to obtain maximum output power. The laser output power and frequency are stabilized by a micro-computer aided feedback control system. In result the fluctuation of output power is less than ?1 % and the fluctuation of frequency is less than ?7 kHz. There is no any frequency drift or power drift during long term operation. A new method for measuring phase shift in heterodyne interferometer is suggested. The phase shift is directly obtained from the probe beam粀hich reflects the variation of plasma density粀ithout comparing with reference beat. The lower limit of measurable phase shift is depending on the frequency of clock and the upper limit is infinite.
