Abstract :
A frequency-doubled Nd:YAG laser is used to study the hyperfine structure of several rovibrational transitions in molecular iodine via modulation transfer spectroscopy. Comparison of two independent lasers stabilized onto separate hyperfine components allows characterization of the stability, reproducibility and possible systematic shifts with pressure and power.<>
