Abstract Beam propagation through a double-adaptive-optics optical system in turbulent atmosphere has been investigated. A typical model of optical systems with the doubleadaptive-optics configuration is established, principles of the two adaptive optics and theory of beam propagation through the optical system in turbulent atmosphere are analyzed. Power efficiency and beam quality (BPF) of the received beam are introduced to evaluate performance of the optical system. Under the H-V 5/7 turbulent model, influences of the two adaptive optics installations are numerically calculated, respectively. Results show that the adaptive optics at the launcher can improve both power efficiency and beam quality of the received beam, the adaptive optics at the receiver can significantly improve beam quality of the received beam. Evolution of the system performance with the increase of adaptive optics correction order is numerically simulated, and results show that the double-adaptive-optics configuration has great advantages in improving beam quality of the received beam in optical systems with beam long-distance propagation through the turbulent atmosphere.

1 Introduction Considerable interest has been exhibited in laser beam turbulence propagation due to their importance in basic science and some attractive applications (Chu et al. 2008; Zhou et al. 2009a; Mahdieh 2008; Toselli et al. 2008; Zhong et al. 2011). The characteristics of beam propagation through turbulent atmosphere have been widely investigated, Mahdieh (2008) has numerically studied the M 2 beam quality factor of Gaussian beam propagation through turbulent atmosphere, Toselli et al. (2008) have investigated performance of beam propagation through non-Kolmogorov turbulence in free space optical system, Zhong et al. (2011) have studied propagation properties of partially coherent Laguerre-Gaussian beams in turbulent atmosphere. Meanwhile, propagation properties of beams with adaptive optics corrections in turbulent atmosphere have attracted much attention (Zhao et al. 2008; Yang et al. 2008). Zhao et al. (2008) have studied performance of adaptive optical communication through turbulent atmospheric,
