Abstract

Based on the application of a relay mirror system, we study the intensity distribu- tion and receiving efficiency of laser beams through a relay mirror system. When Fresnel number is big, this studies shows that the coupling efficiency of power between ground-based telescope and relay mirror is high for collimated beams. Due to small spot and high intensity concentrated on central obscuration, beams focusing to relay mirror is not suitable. For the reason that the distance between the laser source and relay mirror is fixed, and the distance from the relay mirror to a target is various, the intensity distribution is changed with different target. It is impossible to keep in high coupling efficiency when beams focus to target directly through a relay mirror system.
