They've launched satellites that have lasers, but I don't think they've actually demonstrated they have the ability to aim those lasers precisely enough to actually communicate between satellites in orbit.
This statement is meaningless as written. You can emit as much or as little with a laser as you like. You could say "a lot of power is required for a reliable inter-satellite optical link", to which I would say "citation needed".
Iridium has been doing inter-satellite links since the late 90s and moving from RF to optical doesn't change the game that much.
