Abstract
We report absolute frequency measurements of 81 hyperfine components of the rovibrational transitions of molecular iodine at 578 nm using the second harmonic generation of an 1156 nm external-cavity diode laser and a fiber-based optical frequency comb. The relative uncertainties of the measured absolute frequencies are typically 1.4 × 10-11. Accurate hyperfine constants of four rovibrational transitions are obtained by fitting the measured hyperfine splittings to a four-term effective Hamiltonian, including the electric quadrupole, spinrotation, tensor spin-spin, and scalar spin-spin interactions. The observed transitions can be good frequency references at 578 nm and are especially useful for research using atomic ytterbium because the transitions are close to the 1S0-3P0 clock transition of ytterbium.
