Via saturated absorption spectroscopy and thethird-harmonic detection techulque, the hyperfine spectra of127I2 near 532 nm have been observed within the tuningrange of a mini Nd: YVO4-KTP laser. The laser is frequencystabilized against one hypeffine structure (hfs) component of127I2. The analysis of error signal shows that it is possible torealize a bouency stability of 3.0 × l0-l3 at 1 s avrmge time.
