Laser guide stars for adaptive optical system with partial correction

In this article, the number of the artificial guide stars and the brightness of the guide stars used in the partial-correction adaptive optical system with 0.5 Strehl rate(or 0.13 residual rms wavefront error over the subaperture) have been presented. Comparing to the correspondent results of the conventional system, we find that the partial correction system is simple and easy to realize.
