Abstract
A system and method involve using a first laser to generate a laser-induced plasma filament within an optically-transparent medium, using a second laser to generate a communication signal, and using a signal combiner positioned within the path of both the first laser and the second laser to direct the communication signal through the laser-induced plasma filament to a receiver located within the optically-transparent medium.
Claims20
A method comprising the steps of:
- using a first laser to generate a laser-induced plasma filament within an optically-transparent medium;
- directing a communication signal through the laser-induced plasma filament to a receiver located within the optically-transparent medium.
A method comprising the steps of:
- using a first laser to generate a laser-induced plasma filament within an optically-transparent medium using a plurality of high-power, ultra-short pulses;
- using a second laser to generate a communication signal;
- and
- using a signal combiner positioned within the path of both the first laser and the second laser to direct the communication signal through the laser-induced plasma filament to a receiver located within the optically-transparent medium.

A system comprising:
- a first laser configured to generate a laser-induced plasma filament within an optically-transparent medium;
- a second laser configured to generate a communication signal;
- a receiver separated from the first laser and the second laser by the optically-transparent medium, wherein the receiver is configured to receive the communication signal;
- and
- a signal combiner positioned within the path of both the first laser and the second laser such that the communication signal is directed by the signal combiner through the laser-induced plasma filament to the receiver.
