Sending messages to Mars and Jupiter Via Lasers

Sending messages to Mars and Jupiter by beams is now made possible with the help f lasers. Scientists at Nasa have recently developed a new powerful laser with high precision and accuracy that can span interplanetary long distances with great accuracy at millimeters.

The main key here is not making the lasers more powerful rather than making the receivers more powerful making them very sensitive into receiving beams so they can pick up the signals the protons from the background light.
