Paper Abstract

The relationship between the performance of a partial correction adaptive telescope using laser guide stars and the star brightness is discussed. The laser energy requirements for Rayleigh guide star as well as sodium guide star are presented in cases where the diameter d of a subaperture of the telescope is larger than the atmospheric coherence length r0 and the residual rms phase error across the subaperture is larger than 0.63.
