Powerful Laser Guide Star (LGS) systems are standard for the next generation of extremely large telescopes. However, modern earth-based astronomy has gone through a process of concentration on few sites with exceptional sky quality, resulting in those becoming more and more crowded. The future LGS systems encounter hence an environment of surrounding astronomical installations, some of which observing with large fields of view. We derive formulae to calculate the impact of LGS light on the camera of a neighbouring telescope and the probabilities for a laser crossing the camera field of view to occur, and apply these to the specific case of the next very high energy gamma-ray observatory 'Cherenkov Telescope Array' (CTA).
