报道了用频率梳测量碘分子R（34）20-0 a（1），a（10），a（15）超精细跃迁和P（144）23-0 a（1）超精细跃迁的绝对频率。当光源频率稳定在R（34）20-0 a（1）线时，在100 s的积分时间内实现了4 × 10（-12）的频率稳定度。研究了R（34）20- 0a（10）谱线的压力和功率展宽特性。
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.
