Abstract :
Frequency-doubled Nd:YAG lasers have been frequency stabilized against the hyperfine structure components of 127I2 by means of the sub-Doppler frequency modulation technique. A frequency stability of 3×10-13τ-1/2 has been obtained for integration times between 10-3 s<τ<102 s with an estimated reproducibility of about 1 kHz (2×10-12 ). The hyperfine spectroscopy of the rovibrational line P(54)32-0 has been performed and the iodine hyperfine constants have been calculated. The pressure shifts of the hyperfine components α1, α2, α10, and α15 have been measured
