Violet lasers can detect UV-sensitive markings (invisible pens for example)
Yay, I can read the invisible ink for a fraction of a second before the paper catches fire (assuming the violet ones are as powerful as the others)

Don't think lethal is the correct term. Unless maybe you pointed it at someones head for a long period of time, but I think that person would move
A 1+w laser pointer could burn though a paper in a couple seconds, almost instantaneous if the paper is black. You'll get a burn just from shining it over your skin, and cancer possibly. It wouldn't take a long period to do some harm with that.

They look very cool. But what are they intended to be used for? They are definitively too strong for playing around and too weak to cut materials. I am sure there are billions of other uses for lasers but right now none comes to my mind. So a round of question to the interested parties: what would you use yours for?
They're toys for adult star wars fans. Although I wouldn't rate it as a toy as it's as lethal as a gun when used not carefully. You could blind yourself just from exposure to the beam in 1/500 seconds.

It's hard to explain, things don't have to have a practical use to have a value. I know I said in my first post that lasers are not toys, but then again, maybe they are toys for grownups. The magnificent beam in the night sky is a sight that always makes me gape in awe. And the gadget factor is just enormous
Though they do have some actual applications:
Astronomy (Pointing out stars)
Aligning stuff
Signaling
Long range illumination

Those look pretty awesome, how much will you be selling the blue lasers for?
The one I offered when I lauched the website was $189. I wish there was a way to display sold out items and their price on the website in a non-clumsy way, but I haven't found one yet.
I'm drooling at the 2.2w blue laser by survival lasers here : http://www.survivallaser.com/Survival_Laser_II_Special_Edition_445nm_Parts_Bundle_Laser_Components_Only/p556088_5173902.aspx
Any chances of doing something high powered like that?

He's got a little more resources than me, so what he has done is bought a bunch of diodes and cherry picked the most efficient ones, but diodes are expensive, so I doubt I'll reach those powers any time soon. But as said above, 1.8W should be doable, and for much cheaper than the survival laser one.
That being said, there is a new type of blue diode being researched by the community as we speak, discovered in a movie projector. If that turns out to be more powerful than the current diodes in circulation, maybe we will see >2W lasers soon after all!
Price is no issue for me, so long as it's reasonable for the hardware, labor invested, and such. That all being said, if I see some good feedback on your previous orders, would you by chance be willing to build one custom for me? Perhaps a 2W blue 445nm, before you are offering them to the general public? I suppose that might be asking a bit much, but if not, I can certainly wait until you stock them.
Yes, I could do that, but as said I don't really have the money to buy too much stock, so by offering it to you exclusively I'd also have to make the others that might want one wait longer for me to restock, so I think putting it on the website, then first come first serve, would be more fair.
BTW, just put a placeholder on the site for all of your lasers stating the price you'll sell for and the fact that it's 'out of stock'. Hence people could just pre-order from you and possibly pay a small deposit on it. Just removing the page after it's sold seems bad for business
I'm waiting to see your success here!

Yes, higher powered lasers than what I sell is possible, either by increasing current alone (But that would shorten lifetime and duty cycles, so I'm not going to do that), or upgrading components like the heatsink to allow a little higher current, and a high-efficiency lens. But that would of course increase the cost, lenses alone can be quite expensive.
The higher single mode would have to be a violet one, they could potentionally go close to 1W.. But the best for burning is still blue 445nm just because of the sheer power. As said above, a 1800-2000mW laser is doable, and I think I will sell them in the future sometime. (Not cheap though, just saying. It would cost at least $250).

Is it possible to build more powerful handheld lasers? Perhaps a 2w model?
In all honesty, I would like the beefiest laser possible, so I can use it to cut materials like wood, plastic, fabric, etc...
I'm reading here that the violet laser is a single mode, meaning you can focus the laser into a very small point... Are there laser-builds possible that utilize more milliwattage, but still have that feature?

+1 lol. I want the most macho handheld laser on this earth! Rawr!

They are T-rex branded, my supplier states these specs:
I test every pair before I sell them to ensure adequate quality.

Visible Light Penetrated Ratio: >55%
Optical Density: >5.0(OD+5,OD+6)
Attenuation Ratio: 10-6

What brand are your safety glasses? I want to check the specifications of the glasses myself.

That's good to hear. Any information when the next 1.3w ++ blue laser will be in? Also, is the actual light wattage is 1.3w (measured via a laser meter)? I'm planning to pick a high powered laser just for fun, and was looking at wickedlasers before I saw yours.
I think I'll order new parts for blues within a few days.
Yes, the powers stated on the website is the actual powers. I don't have an LPM, but diode lasers, given a certain current, will always output the same power within a small tolerance. I guarantee that the 1300mW one will never go below 1200mW, and usually it will be more powerful.

I can't help but notice you're using CREE drivers, right? (it's on one of those pics) IMHO, cheap cree drivers are really meant for led's and the such. Maybe try using one of those quality lasers by Moh's or DTR? 
No, I'm not using Cree drivers, only the flashlight host. I'm using Mohrenbergs's linear driver, don't worry
Alright, I'll bite, I'm a sucker for laser gadgets.
Order placed, discount applied, bitcoins sent. Will report back if/when the device arrives and if it hits their specs after testing.

Thanks! I will pack it up and send it your way monday.

Do you offer an option with a bigger heatsink, and a detachable collimator?
I don't offer different heatsinks atm, but I will probably offer at least copper heatsink upgrades in the future. The lens is already detachable, you can install any aftermarket lens that fits aixiz modules (m9 x .5 pitch threading). I'll probably offer upgraded lenses myself too. A 1800-2000mW blue laser should be doable with the right parts.
