I'm a bit surprised this stuff is still legal to purchase:

"Flare" Red Laser Pointer 50mW - 200mW:

The smaller lasers, 100mW and under, have to uses a lens to focus the beam, but at around 150mW to 200mW no lens is needed. As always, eye protection is a must, but some of the YouTube videos show people NOT using eye protection. A laser > 5mW can blind you in a split second.

My first CD player, a Sony D-5 (1984), came with a postcard to register with some federal authority... So did the first Pioneer Laser Disc player!

20 years ago I bought my now ex wife one of those cheap $10 laser pointers for her class (she's a teacher.) She didn't want it because it was cheap and would quit working. Had to have some special one that all the other teachers had. My wife uses it every day to play with the cat for the last 14 years. I've changed batteries in it only once. I smile every time she uses it.

Those super power lasers pose a quandry to me and to other grown ups, I'm sure. They are so neat that we all want one and wouldn't try to blind an airline pilot or the cat. Sadly, many others are not so inclined. Someday soon I'm very afraid some idiot will cause a plane to crash or crash land. Having said that. I'd still like to have one for myself.

I don't presently have a cat. But, those low power lasers are the BEST cat toy I ever had.

I've looked at the high power green lasers. Just window shopping. I can't justify paying their price for something which, for me, would be nothing more than a toy.
There's not as much disposable income here as there used to be.

... and, you sure as heck wouldn't use one for a cat toy.

LoL! Would add a new dimension to the "it's just light, you can't catch it" angle
I have a cat that loves lasers to. Also have a border collie mix that unlike most other dogs, never tires of "herding" the dot.

I find myself thinking that some day some #$$#%^$% idiot is going to cause something horrible to happen and the high powered stuff will no longer be sold. So I want to get one and have a chance to play around with it before that happens.

While a $200 1 watt blue laser would be very cool, I'd be happy with a $99 150mW red laser.

Once you go above 5mW, laser safety is mandatory if you want to keep your eyesight. The video is 1 hour long, but is very good in addressing the issues with laser safety:

Let me explain eye protection required. That means special lazer glasses that keep you from burning holes in your retina's if you are accidentally exposed. Most high powered lazer light is invisible. It's in frequencies you can't see with the naked eye. That's what telecoms use to send you internet over fiber optic. That stuff doesn't give you a 2nd chance. Look at it and say good bye to your eye sight. Lazers also reflect around the room off of shiney objects. That can hurt you as well. Play with this stuff at your own risk!

The better quality lasers have IR filters; however many of the cheap lasers that come out of China save a few cents by not putting in the filters. The better quality safety glasses should also offer an IR block, but the cheap laser safety glasses don't.

Safety Glasses are an intelligence test. Stupid people will fail the test and go blind!!!

I have a green one that is probably illegal, it is insanely bright in the night sky.

I believe it is the blue and purple lasers that output the most 'invisible' damaging light.

The high powered green and red ones are dangerous when they go directly into your eye, the blue and violet ones are dangerous regardless of whether they are aimed at you.

One of the local stores does sell 100mW green lasers, but right now they are out of stock. They should get some in a few weeks. My guess is that the maker says it's 100mW, but it's likely around 35mW, enough to be dangerous. A co-worker got one and showed it to me. Compared to my 5mW green laser, this thing is super bright.

I hope by next month they get more in stock, but I'm sure the store doesn't sell safety glasses or care who they sell this to. If they keep selling this, I can see this is going to end badly.

Wow, it's been a couple years since I checked. It looks like the place I was thinking about has lowered the bar a bit. Last I checked, they had 1.5 watt units, now they're at half that. "only" 750 mW (for a grand).

What a rip. I bet if you have your heart bent on bringing down airliners, and such enough, you could still find the 1.5 Watt units, LOL,
