| Abstract | We have designed and assembled a saturated absorption-spectroscopy system of for the frequency stabilization of the 543 nm He-Ne laser. The frequency of a internal-mirror 543 nm He-Ne laser was swept by utilizing the temperature and PZT change of the laser cavity length. Frequency modulation was applied to the output laser mirror with a PZT modulator for the third harmonic signal. A portion of the hyperfine spectrum originated from the R(12)26-0 and R(106)28-0 transitions of the B-X system of was observed as the third-derivative signal using a saturated absorption spectroscopy. The signal-to-noise ratio of a typical hyperfine spectrum signal was estimated to be 30:1. |
