title: Absolute frequency measurement of the molecular iodine hyperfine components near 560 nm with a solid-state laser source.
abstract: We report absolute frequency measurements of the molecular iodine R(34) 20-0 a(1), a(10), and a(15) hyperfine transitions, and the P(144) 23-0 a(1) hyperfine transition at 560 nm with a frequency comb. The light source is based on an all-solid-state frequency quadrupled laser system. A frequency stability of 4x10(-12) is achieved over a 100 s integration time when the light source is frequency stabilized to the R(34) 20-0 a(1) line. The pressure and power broadening dependences of the R(34) 20-0 a(10) line are also investigated.
