Abstract:
Provided are a device and method for free space coherent optical communications by means of an automatic compensation for phase noise in atmosphere using a femtosecond laser optical comb, and more particularly, a device and method for free space coherent optical communications by means of an automatic compensation for phase noise in atmosphere using a femtosecond laser optical comb, in which a phase shift value due to atmospheric turbulence is obtained from reflected light of transmission light generated from a femtosecond laser optical comb and the transmission light is pre-distorted on the basis of the phase shift value, thereby pre-compensating, in a transmission end, for phase noise due to atmospheric turbulence.

Claim (Index 5):
The device of  claim 1 , wherein at least one of the first laser light and the second laser light is cw laser obtained by extracting and amplifying one optical frequency mode from the optical comb generated from the femtosecond laser light source having stabilized repetition rate and offset frequency.
