You might be thinking of the microwave radiation used to power the 
"Great Seal" type bugs. I think that required a fairly powerful 
microwave beam. Though it seems like it would be safe for the spy so 
long as he kept away from the front of the antenna/waveguide and the 
equipment was well designed for safety (not a given in the USSR). 
OTOH, actually looking out the window at where the laser is might be 
dangerous to your eyesight (and looking at the reflected laser from 
the spy's viewpoint could do the same).

That would probably help reduce the vibration transmitted to the 
outside window. Various window films on the outside glass might either 
absorb the laser or reflect it, either of which could make it less 
effective.
