Abstract
The precision spectroscopy of the iodine transitions at 556 nm will benefit research on Yb cold atoms owing to the frequency coincidence of the iodine hyperfine transitions and the 1S0-3P1 spin-forbidden transition of Yb. We perform Doppler-free spectroscopy of hyperfine structures of molecular iodine using the second harmonic of a 1112-nm diode laser.
