:crackup: rhd, you and the other self-proclaimed, basement-dwelling 'white knights' really do crack me up. I'd be surprised if you had enough neurons between yourselves to rub them together and realise I could just BUY a high powered laser from any of the numerous online stores. Instead I...

Okaaaay, buddy, perhaps you should go back to exposing 9/11 conspiracies? There's nothing contradictory there, Sherlock. Pairs come up, then they go... if they're not bragging about how cool it is to everyone else then it's not going to create much interest. Nevermind the fact that I was...

Every lab-style laser of comparable power that I've seen so far has been more expensive. Handheld lasers are available for quite a reasonable price. Set it up with a mount, and that's it. Problem?

Look, we've got our setup pretty well planned. We know what we need, and we know how to keep things safe. I'm not here to explain myself to the laser Gestapo. It's not like we're letting kids play with or even touch the lasers. It's all being supervised/approved by staff/lecturers anyway. The...

Uhm, please don't take us for idiots. Although we have an ok budget, we can hardly afford to buy 100 pairs of safety glasses and everything else on top. We are taking kids in pairs to the small 'range', which is cordoned off from the rest of the hall with some barriers. Anyway, I've already...

Uhhh, ok, kiddo. For one, all beams will be pointed downrange towards a special black screen, not in every random direction. Secondly, we already have plenty of safety equipment and it is being taken very seriously as I've stated numerous times. I came here for advice on lasers. If I needed to...

Yeah, as mentioned I already have a couple of intermediate red lasers. Someone else will get the green, and I will get a blue one. I think that will be enough... no need for any of the other variants. :) We have an ok budget for this, so come on, might as well get some of the better lasers out...

I've done these 'science week' stands before, and I know what kids want. They want to be impressed. Otherwise they get bored and go somewhere else. So, yes, we'd like to pop and burn some things, as well as all the other stuff. Anyway, I really didn't come on here for a lecture on safety (I'm...

Nah, really not interested in playing around. It's not a lab project. It's a personal project related with some optional credits I'm taking. We're hosting a science week for some secondary school kids and we want to show off what lasers can do. And yeah, there'll be plenty of information on...

Hi. Yeah, I saw that thread, but I thought it was a bit expensive ($240?)... It's $220 from the Dragon Laser website. The shipping cost from them isn't too bad and the delay shouldn't be too long (I don't need it urgently anyway), so it would need to be lower than what it is on there.

Hey guys! I'm a university student and I've got a project for which I'm going to need a reliable, high powered (~1W) laser. I'm looking to buy a complete package ('blue' laser, rechargeable batteries, charger, safety glasses, etc). I'm not particularly interested in building one myself (though...
