That's a more interesting idea but still quite questionable, given how expensive sending anything to space is, and then maintaining it.
It made more sense with solar was expensive per square mm, but that is no longer the case.
Also, transmission is a huge problem. It's easy to say 'make a maser,' but making giant one and aiming it reliably (lest one fries nearby terrain as the satellite moves to track the sun), and making a receiver big enough from how much the laser spreads out from geosync orbit is a tall order. Geosync is super far away.
There's plenty of space on the ground, for now.
