Like other commenters, I unfortunately don't think that's true.
The Wikipedia [1] page says:
To build a permanent airfield at Troll, the Norwegian Polar Institute bought a snow groomer and a tracked vehicle with a snow blower, flatbed and ice cutter. The works was organized with a land-based Global Positioning System laser system.
So that might very well be where the idea that the actual cutting was done using laser came from. I wasn't able to quickly goog up some example of what it probably was (an accessory on some kind of tracked heavy equipment), but perhaps someone else knows?
They probably mean a laser-based "grade control system" - such as the Trimble GCS900, CAT Accugrade and similar.
The idea is, instead of having the heavy equipment operator move some dirt then someone following with survey equipment and telling him he removed too much or too little, the survey equipment is mounted right on the blade/bucket and automatically gets the height right on the first pass.
And of course there are much more sophisticated systems available including automated control of the blade. Pretty much standard equipment on any construction project today.
