Basschefers, I don't know whether you're information is correct or not, because I've never been on the receiving end of a laser, however I'll recount a story told to me by a 737 Captain who I've known since his student pilot days, and you can decide for yourself.
While on approach into an Australian airport his aircraft came under laser attack, and his co-pilot was so severely distracted she was unable to continue flying the aircraft. The Captain had to make the landing while doing both the pilot and co-pilot jobs, as the co-pilot was no longer capable of safely flying the aircraft.
You'll note that I haven't identifed the airline or city involved for deliberate reasons, but the Captain describes landing at the airport as being 'technically difficult anyway' and the laser attack seriously jeopardised the safety of his aircraft. This pilot stated he has been on the receiving end of lasers a couple of times and described them as being a serious distraction in the cockpit and quite dangerous. For his airline, lasers are a significant safety issue.
Unfortunately if the information our friendly 737 Captain is correct (and I have no reason to doubt his word) then defence lawyers acting on behalf of laser attackers will use information gained from forums such as this, and these academics to dismiss laser attacks as nothing more than a storm in a tea cup. If major airlines are worried about laser attacks, then I think we should perhaps take notice of them.
Maybe the academic you have quoted would have a different opinion if he had been the victim of a laser attack while on final.
Cheers
