摘要：

We describe in this paper the development of a simulation tool for modeling any kind of adaptive optic system with laser guide star within the framework of the European network Laser Guide Star for 8-m Class Telescopes. This is intended to support investigations about laser guide stars problems like cone effect and tip-tilt determination. The different kind of software modules to be developed are listed and the libraries already distributed among the network are described: phase screen generation (with fast Fourier transform and Zernike methods), downward propagation (for natural and laser guide stars), wavefront sensing and reconstruction (with Shack-Hartmann and curvature sensor of various geometries). The future studies for serving the cone effect are also presented.
