Not much info on the laser itself, but I assume the divergence must be awesome!
NASA beams Mona Lisa to moon with laser - CBS News
The laser signal, fired from an installation in Maryland, beamed the Mona Lisa to the moon to be received 240,000 miles away by NASA's Lunar Reconnaissance Orbiter, which has been orbiting the moon since 2009. The Mona Lisa transmission, NASA scientists said, is a major advance in laser communication for interplanetary spacecraft.
