Abstract :
Hyperfine structures of the R(122)35-0, P(84)33-0, P(104)34-0, P(55)32-0, and R(58)32-0 transitions of molecular iodine near 532 nm have been observed on the red end of the tuning range of the frequency-doubled Nd:YAG lasers. We have obtained excellent signal-to-noise ratios of the hyperfine structures by using modulation transfer spectroscopy.
