How was the laser used to make landing easier in bad weather? Why was it a
"no-no in many places?"

Laser Ranging could be used in place of the Radar Azimuth and Elevation locks to
provide more precise targeting and position updating info. In Landing Mode, it
updated the aircraft position relative to known offsets (e.g., an arresting gear
engine or radar shack near the runway). As long as the humidity was low enough
to allow laser penetration, it worked well.

However, if the offset was a manned building, or an LSO was on station at the
runway, shining the Laser at him would be ungood...
