Patent ID: 7991294

Claim:
Bi-directional laser communications system comprising a first transceiver and a second transceiver for establishing two optical channels there between, wherein said first transceiver comprises a first transmitter with a pulsed high-power laser source for transmitting optical beacon pulses into a first of said optical channels, said second transceiver comprises a receiver with a receiving optic for receiving said optical beacon pulses, said second transceiver and/or a receiving optic of said second transceiver being adjustable so that it can be adjusted with respect to the direction of said optical beacon pulses, a second transmitter with a laser for transmitting a high energy laser signal into a second of said optical channels, and means for synchronization of said first optical channel and said second optical channel, said means preventing said high energy laser signals from being transmitted into said second optical channel whenever said optical beacon pulses are expected to arrive through said first optical channel.
