Abstract
An improved adaptive optics system is disclosed for correcting atmospheric phase aberrations. A satellite (10) laser beacon is operated at the Stokes shifted Raman wavelength. After passing through the atmosphere (A), the signal is phase conjugated (16) and amplified in the Raman amplifier (12). The result is a high energy laser beam with phase conjugated aberrations which may be returned to the satellite (10).
