Using laser beams within the solar system to find distances to celestial objects is possible but the length of time needed could be exceeding long for real communication.

Question

Quizplus · Accepted Answer

While laser beams can be used to measure distances within the solar system, it would take an exceeding long time to use them for communication purposes. The speed of light is finite and while it is very fast, it still takes time to propagate across large distances in space. For example, it takes about 3 minutes for light to travel from the Earth to the Moon. If we were using a laser to communicate with a distant planet, the round-trip time for a signal could be in the range of minutes to hours or even longer depending on the distance involved. This would make real-time communication difficult, if not impossible, using lasers alone.
