Laser communication transceiver and system

A laser communication transceiver for transmitting information via laser beams to other laser communication transceivers and for receiving information via laser beams from other similar laser communication transceivers comprising:

• A) at least one wavelength controlled beacon laser means for producing at least one beacon laser beam at a predetermined narrowband wavelength defining a narrow band beacon wavelength,
• B) a laser transmitter system comprising:
• 1) at least one laser means for producing a signal laser beam,
• 2) a signal modulation means for modulating said signal laser beam to impose a communication signal on said laser beam,
• C) a laser receiver means for receiving laser beams transmitted from said other laser communication transceiver comprising:
• 1) a telescope means for collecting laser beams transmitted from said other laser communication transceiver,
• 2) a beacon receive means, comprising an atomic line filter matched to said narrow band beacon wavelength, for detecting and determining the direction of beacon laser beams transmitted by said other similar laser communication transceivers,
• 3) a laser signal receive means for receiving signal laser beams transmitted by said other similar laser communication transceiver,
• D) a gimbal pointing means for pointing said telescope means toward said other laser communication transceiver in the direction determined by said beacon laser means.
