  • Method and apparatus for locking the wavelength of beacon beam in a free-space laser communications system
    Patent number: 6151340
    Abstract: A method and apparatus for setting the wavelength of a laser beacon in a free-space laser communication system. The invention uses the absorption and transmission attributes of a material, such as cesium, to generate a physical environment at the transmitting transceiver that essentially exactly replicates the environment that governs the physics of an atomic line filter at a receiving transceiver that is based on the absorption and transmission attributes of the same material.
