Abstract

We report absolute frequency measurements of the molecular iodine R(34) 20-0 a1, a10, and a15 hyperfine transitions, and the P(144) 23-0 a1 hyperfine transition at 560nm with a frequency comb. The light source is based on an all-solid-state frequency quadrupled laser system. A frequency stability of 4×1012 is achieved over a 100s integration time when the light source is frequency stabilized to the R(34) 20-0 a1 line. The pressure and power broadening dependences of the R(34) 20-0 a10 line are also investigated.
