A 1.5$~\\mu$m laser is frequency tripled in order to excite the molecular transitions at 0.51$~\\mu$m and frequency locked on a hyperfine line. With this frequency reference, we report short-term stability about $3\\,\\times\\,10^{-14}~\\tau^{-1/2}$, with a minimum value of $4\\,\\times\\,10^{-15}$ at 200~s. The lower part of $10^{-15}$ frequency stability domain is reached, in our case, only by adding an efficient magnetic shield around the sealed quartz iodine cell.
