Great Scott! (Whoa, this is heavy.)
There's a lot of debate on the topic, but purportedly at geostationary distances the maser beam spread would be sufficient enough that harms would be pretty small and mitigable ... perhaps even negligible compared to those of legacy energy sources. I'm not going to try to link a lot of resources, I'd just be googling for them same as you.
