We report here experimental results obtained in saturated absorption spectroscopy of iodine in a low pressure cell at 501.7 nm. We obtained lines of 30 kHz wide (HWHM) for the R(26)62-0 transition, which are, to our knowledge, the narrowest resonances ever observed in iodine spectroscopy in cell
The experimental set-up for high-resolution spectroscopy of iodine at 501.7 nm, near the dissociation limit, is described. Line shapes of about 30 kHz wide are obtained with hyperfine components of the R(26)62-0 transition. Preliminary results on the absolute frequency measurements of the Ar+ laser locked onto these transitions are given.
