It is proposed to use the wavelength 1.315μm of the laser transition 2 P 1/2 → 2 P 3/2 in atomic iodine both for passive and active SETI. The search for an extraterrestrial signal at this wavelength is promising because an active quantum filter (AQF) with a quantum sensitivity limit and with strong fixing in the spectrum luminescence line of the width less than 0.01cm...
