It is proposed to use the wavelength 1.315 μm of the laser transition 2P1/2→2P3/2 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) w

It is proposed to search for signals from extraterrestrial intelligence (ETI) at a wavelength of 1.315 μm of the laser 2P1/2 → 2P3/2 transition in the atomic iodine, which can be used for this purpose as the natural frequency reference. The search

The effect of background light on the sensitivity of a laser receiver with an iodine active quantum filter (λ=1.315 μm) was theoretically and experimentally investigated. Upon the reception of a 40-ns pulsed signal against the background of 2.5-fol

The effect of a wide-range background exposure on the sensitivity of a laser receiver with an iodine quantum filter (λ =1.315 μm) is theoretically investigated. The sensitivity of the laser receiver is shown to be only about 12% less than the quant

A laser receiver (LR) with an active quantum filter (AQF) (? =1.315 ?m) based on an iodine photodissociation laser is studied. It is shown that the LR sensitivity can be brought up to the quantum detection limit by increasing the AQF gain. Taking int
