I don't know much about lasers but surely there must be some kind of glass/plastic that can be put on the cockpits that would block a laser beam?
-
Or don't point the sweet green industrial lasers at aircraft in the first place if your bellybutton doesn't want to go to jail as a felon.
We aren't talking about little laser pointers or crimson trace grips either.

There's always a notam for laser light shows near Tampa, and of course the lockheed laser testing facility near Orlando.
-
Many high-powered lasers can completely incapacitate pilots
Really? How powerful does it need to be?
I'd think such a powerful laser would be too expensive for a normal person.

Get hit by one.
The green industrial size lasers are easy enough to come by it seems given the number if incidents. They can, will and have blinded folks while down low which is something you of course don't want during a critical phase of flight.
Here are some examples of small hand held lasers being used.

Holy $h1t, I had no idea it's that noticeable.
What's an industrial size laser? ~1000mW?

Golfer,
Is it only the "green" lasers? I wonder if the red laser levels on the market these days would cause an issue. I've seen a few that you didnt need the safety glasses to see at all,they were used to shoot line for walls in large highrises!
:salute
-
Red light does not interfere with your night vision so it should not be that bad, but given that it's a focused bright beam it can still cause problems.

I don't really know much about the technology or specific. Just that the bigger badder ones seem to have all been green. Can't say.
The red laser light wouldn't be a good thing, the specific reason your eyes wouldn't be as affected nor would it be an acceptable thing to do. I think the technology is less powerful is all but don't know why or how.

"For the Division Bell tour in 1994, Marc Brickman wanted to retain what had worked in the past, thus propagating the Floyd concert legacy of musical and visual extravagance, while enhancing the show by making use of the very latest and greatest technologies at his disposal. But for Brickman, that doesn't always mean technologies "currently" available to the entertainment industry, and sometimes he has to look outside the box to fulfill his visions. When interviewed for Lighting Dimensions' September 1994 issue, Brickman comments on his laser upgrade for the new tour after a trip to Hughes Aircraft:
"Being an American, I listen to all the propaganda that our news media puts out, so as they said something about how they were reducing the defense budget and trying to turn the defense into commercial applications. I figured maybe I could go out and buy some "Star Wars" lasers," Brickman says. "And at the time that I was doing that I got a call from Mark Loman at Rocklite describing this laser. So, I went out to Toronto and saw it, and thought it was great. And I have 2 complete, 50W, copper-vapor laser systems."
(In fact what the Floyd bought for the 1994 tour were two Oxford Laser ACL 45 Copper vapor lasers. The ACL 45 is a big laser. The laser heads are 2.526 meters (99.4") long by 28.2 cm (11.1") by 37.0 cm (14.6") and weigh 145 Kg (651 lbs.); the power supply units are 67.5 cm (26.6") by 65.2 cm (25.7") by 75.9 cm (29.8") high (including the wheels) and weighs 230 Kg (506 lbs.) These units give 45 watts of laser output each from only about 7Kw of electrical power.)"
The ACL 45's were awesome to see in person and even then it was known that where ever they were playing in the US.....the FAA required a 50 mile radius around the venue when these lasers werre used. IIRC it was all in the timing. The lasers were from the defunct Star Wars program of the 80's. Both shows were incredible.

:O
If I was in FAA's shoes I just would not allow them to use those lasers.

Why? They used them to perfection. Apple created three Mac Systems that were unavailable to the Public, specifically to use for the Tour (fastest CPU's from the R&D dept.). Those two shows are still the loudest concerts I have ever been too and I have seen plenty. Gilmour's intro to "Sorrow" went through your chest like a scalpel through butter.
Marc Brickman is the premier Stage Builder in the World. He makes the impossible happen and caters to the artists.

There is nothing wrong with the show. I'm thinking about all the pilots that that TFR (Temporary Flight Restriction) gave trouble too. 50 miles radios is a large area, you can't just fly around it. And since TFRs are not always there there is a possibility that someone did not know about it, in that case it's possible that someone could have have their licence suspended for a few month by flying in that area.

At the designated times, they enforced the no fly-over. For the rest of the show, the planes went about their business.

the lock up the spray paint, but the lazer are easily sold out of ice cream trucks.

They could not have known the exact time the laser would have been used to it's possible the TFR to up a significant period of time.

The lasers were only used during 1 or 2 songs and yes, their shows did NOT vary in length. The link I posted explains it and also informs you of how powerful the Copper color laser was.....
But yes, during those one or two songs, no Air Traffic in the vicinity (I do not know the exact figure) because of how powerful they were.
Edit: "With a similar divergence to argon lasers, a Copper Vapour laser beam keeps it's size for long distances. One consequence of this is that when the tour is playing at open air venues and is projecting unterminated beams, it has to work with local Air Traffic Control to declare an exclusion zone around the stadium." Mind you almost 1/2-3/4's of the venues............were open air.
They used these exact lasers to remove the "twinkling of stars" in pictures, because of the disruptive "atmosphere" they caused. As far as I know, Pink Floyd were the only ones to ever use this "potent" of a laser.

I just don't have enough information to continue a factual discussion, without that it would just be us saying "yes" and "no". My opinion that I stated on the previous page is very biased.
Information that I'd like to have in order to discuss this:
- Requirements to issue a TFR, specifically how far in advance you need to request it
- How specific was the plan for the show, could it have been delayed by a few minutes or did it have to start at the exact second as planned
- How far in advance that TFR was actually issued
- How long was that TFR issued for
- The amount of aircraft that normally fly though that area in the time span the TFR was issued for

Uhh, that much thought doesn't happen even today. You're basing your keystrokes on some big assumptions without considering the world of aviation in even the 1990s was very different than the post 9/11 we know today.
Laser shows are common enough and themselves aren't a big deal as their lasers aren't aimed at and track aircraft like the criminals mentioned earlier.
You're thinking too much and not enough at the same time it seems.

Your right, I was not thinking about the time period at all.
-
I've never seen a TFR specifically for a laser show either. Just a NOTAM. That seems to work fine.

...and I also assumed that it was a TFR when he said "FAA required a 50 mile radius around", very likely it was just a NOTAM.
I guess I can take back everything I said in this thread. :bhead

I'd think such a powerful laser would be too expensive for a normal person.
1000 milliwatt green laser pointer is 50 bucks from China, free shipping.

Has anyone ever looked at a laser beam through night vision binoculars? It looks like something out of star wars :rofl

Electrochromic Glass: Instant Darkening
Velux has developed electrochromic glass that darkens instantly when you flip a switch. Available now with additional sizes to be offered later this year, the glass works by applying an electric current to its special layers, which then turn dark, blocking out sunlight and its associated heat. Perfect for skylights, with this technology you can do away with shades and blinds, letting you electronically control when it's dark in your room and when it's not.
http://gizmodo.com/190931/electrochromic-glass-instant-darkening
Using something like this with embedded light sensors, and possibly even the ability to manipulate individual cells would be a great way to block this out and have a minimal amount of light slip through. As the US military is using similar technology (Optical Laser) in weapons development for both Anti-Aircraft and Crowd Control purposes, I'd say development of a countermeasure won't be far behind... I'm sure our systems will be made in China, so we'll be sure to see whomever we're fighting next using them on us.

THESE LASERS ARE SERIOUS watch what this one does to 23 balloons. now put it in your eye...

see this. I've gotten a couple lasers from them

I don't even want the Arctic, that is too much power for someone as dumb as me.

Do those lasers have any real purpose or is it just a "toy"?

This last Independence Day, my family and I celebrated on the Oregon coast. We were on the beach and the fireworks were located on a jetty. There were a number of boats anchored maybe 600yds off shore and when it started getting dark one of them fired up a green laser. It was powerful enough to easily cause eye damage. He kept it pretty much pointed up. However after a few minutes we could see a CG skiff head for his boat. After being along side his boat for a few minutes they cruised up past the other boats then headed back to the mouth of the harbor. We didn't see the green laser anymore. I can only guess why. I don't know if they did or even could stop him from operating it or not.
I know a little bit about lasers and quite frankly I was relieved he desisted.
