The minimum laser pulse energy to detect sand-dust with the polarized 532 nm perpendicular channel and 1064 nm channel with airborne atmospheric lidar are analyzed statistically according to American ANSI standard and sand-dust extinction coefficient profiles detected by ground-based lidar from 1999 to 2004 year in Hefei area. The laser pulse eye-safety maximal energy with different beam divergence angles and energy ratio (532 nm and 1064 nm) are simulated in 0～12 km altitude is simulated for the airborne atmospheric lidar. Two laser pulse energy distribution schemes are presented according to the eye-safety standard on the ground, detection ability for two “bottle-neck” channels and statistical results of sand-dust extinction profile in Hefei.
