Not so much.  You would need to focus the beam further as well.  Current
tech can focus well enough for wireless transmission to a relatively large
antenna on the ground, but for a weapon you would need much tighter focus,
unless you want to raze cities or similar (for which nuclear weapons work
better - and the nations which have a realistic shot at developing
space-based solar power already have nuclear weapons).
