Transport Canada is trying to find out who has been pointing laser pointers at airplane pilots over the last few days.
There have been at least six instances recently where pilots landing at Montreal’s Trudeau airport have been distracted by a green laser pointer.
The device, which can be purchased for $100 and has a range of three kilometres, can blind airline pilots, so Transport Canada considers it a serious safety risk.

As a laser physicist, I investigate Physics in and with lasers, and develop new type of lasers. But I have never own a laser myself, not even a laser pointer. Recently, I got one from Techlasers. It is a Infiniti II 95mW, comes together with a dragon case and a goggle. It is slim and light, and take two AAA batteries to power. The beam is very clean and nice.
What I tried to do first is to take laser photos, as those cool people did. But it quickly turns out not an easy task. 
I pointed the laser to my fish tank. Poor golden fishes, I hope they were not frightened. But apparently, they avoid the laser beam well. They didn’t show up in my photos at all. All of my photos were blurred, because I took photo with one hand while another hand holds the laser pointer. I guess to really get good pictures I need kind of tripod for both my camera and the laser.
What do you think is in the following photo?
It is a bath towel. Interestingly, it looks deep, but actually flat.
Later I tried to point to objects like cups and bottles, etc, which are common subjects of laser photography. But the results are not as good as I have hoped. I need to learn photography. 
I haven’t dare to point to sky or play outdoor yet, because I don’t know if there is any local regulation on usage of lasers.

The internet trading companies eBay and Amazon are removing high-powered green laser pens from sale on their sites.
The move follows a BBC investigation which found some of these potentially dangerous products were being sold irresponsibly by individual traders.
Many listings describe the pens as toys or, in one case, “wicked gadgets”.
But RAF and police helicopters have been among dozens of aircraft targeted by these devices, which can send a beam several miles, dazzling pilots.
EBay told the Donal MacIntyre programme on BBC Radio 5 live it had become “increasingly concerned” by reports of these lasers being used for “wholly inappropriate purposes”.
Amazon.co.uk said it would “remove the listings for these products as quickly as possible”.
PILOTS have called for super-strong laser pens to be properly licensed after serious concerns were raised about incidents where pilots were briefly blinded by the gadgets.
Aviation bosses say they want the lasers, which breach UK safety limits on the strength of laser pens by as much as 200 times yet can cost as little as £10, to be treated in the same way as firearms following a close-call incident where passengers safety was threatened.

A HASTINGS flying instructor believes NSW should follow in the footsteps of Western Australian and declare hand-held lasers “controlled weapons” after an incident in the skies above Port Macquarie.
Yesterday, the Western Australian Police Minister John Kobelke declared laser pointers to be ‘controlled weapons’ with fines of up to $4000 or 12 months jail for their illegal use.
It is a move that will strengthen the push in New South Wales to have the hand-held devices officially banned.
