Abstract: A pulse laser system utilized for communication transmits a modulated pulsed laser beam having a precise wavelength to match a receiver. An etalon is positioned in the resonant cavity of the laser and is adjustable to tune the laser. A continuous wave reference beam is provided and is compared with the laser output beam and if the wavelength's bear other than a predetermined relationship with respect to one another, a control signal is generated to adjust the etalon in the laser resonant cavity. In one embodiment another etalon is placed in the reference beam path as well as the laser beam path with the transmitted beams being detected in order to derive normalized proportionality factors relating to each beam so that a comparison of the proportionality factors may be made and utilized for control purposes.

Abstract: A laser communication system in which a filter-detector is provided which has a high acceptance angle and a narrow bandwidth. The filter-detector contains vaporized selected atomic species or a molecular composition dissociable to the selected atomic species. The selected atomic species electronic ground state is not absorptive of the laser output wavelength, but the selected atomic species exhibits a metastable or long-lived energy state which when populated absorbs the laser output wavelength. A subsequent transition produces fluorescence from the atomic species as a function of the laser output.
