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
