  • Laser phased array technique on coherent combining of multiple beams faces challenges when applied in propagation through the long-range atmosphere. Aberrations in such transmission systems include turbulence-induced dynamic aberrations located at the path from the fiber laser array to the target, besides the inherent phase errors like phase noises and tip/tilt errors. Effective bandwidth for eliminating such aberrations is limited by the optical transmission delay and the increment of the array scale. Existing techniques, e.g., target-in-the-loop and delayed stochastic parallel gradient descent, are difficult to deal with the fast-changing turbulence-induced tip/tilt aberrations. But correcting these aberrations is critical for obtaining combined laser beams on the target with the best beam quality. In this paper, research progress of multi-aperture laser transceiving control for beam combining applications in IOE, CAS was This method provided efficient ways to achieve tip/tilt control for the beam coupling from space to fiber and the outgoing laser beams in the beam combining applications. Correction of the aberrations outside the fiber laser array based on active multi-aperture wavefront sensing of the fiber laser array was proposed. These novel techniques presented here would promote the application of laser phased array technique in atmospheric propagation.

Abstract: Laser phased array technique on coherent combining of multiple beams faces challenges when applied in propagation through the long-range atmosphere. Aberrations in such transmission systems include turbulence-induced dynamic aberrations located at the path from the fiber laser array to the target, besides the inherent phase errors like phase noises and tip/tilt errors. Effective bandwidth for eliminating such aberrations is limited by the optical transmission delay and the increment of the array scale. Existing techniques, e.g., target-in-the-loop and delayed stochastic parallel gradient descent, are difficult to deal with the fast-changing turbulence-induced tip/tilt aberrations. But correcting these aberrations is critical for obtaining combined laser beams on the target with the best beam quality. In this paper, research progress of multi-aperture laser transceiving control for beam combining applications in IOE, CAS was This method provided efficient ways to achieve tip/tilt control for the beam coupling from space to fiber and the outgoing laser beams in the beam combining applications. Correction of the aberrations outside the fiber laser array based on active multi-aperture wavefront sensing of the fiber laser array was proposed. These novel techniques presented here would promote the application of laser phased array technique in atmospheric propagation.
