ABSTRACT:
A laser communication device for transmitting and receiving information imposed on laser beams. A transmitting unit and a receiving unit are implemented based on atomic line filters. The transmitting unit includes a compact tunable laser locked to a selected atomic transition line. Information may be imposed on a laser beam by modulating the frequency thereof while maintaining its output power substantially unchanged.
