Frequency-doubled Nd:YAG lasers have been frequency stabilized against the hyperfine structure components of I-127(2) by means of the sub-Doppler frequency modulation technique. A frequency stability of 3 x 10(-13)tau(-1/2) has been obtained for integration times between 10(-3) s < tau < 10(2) s with an estimated reproducibility of about 1 kHz (2 x 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 a(1), a(2), a(10), and a(15) have been measured.

Abstract
Frequency-doubled Nd:YAG lasers have been frequency stabilized against the hyperfine structure components of I-127(2) by means of the sub-Doppler frequency modulation technique. A frequency stability of 3 x 10(-13)tau(-1/2) has been obtained for integration times between 10(-3) s < tau < 10(2) s with an estimated reproducibility of about 1 kHz (2 x 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 a(1), a(2), a(10), and a(15) have been measured.File in questo prodotto:
