Portable 1W Laser for Sale

so hypothetically someone could set fire to any church sign with this from a discreet distance and there wouldn't be any forensic evidence left, leaving the only possible outcome of an investigation as an act of God.

Awesome
:D
 
Setting it on fire would not be easy .. but writing funny messages could work. I would recommend astronomic telescope with motorized axises and software which allows manual tracking.
Under several hundreds meters, focus is only thing which steal power .. I've seen video where some guys lit fuse of rocket with 500mw green laser over 400m distance, using what seemed to be 70mm diameter telescope.
Still I did not manage to focus my 200mw red through my 112mm telescope. The field is distorted and it has no power at all.

I wanted one of these things until I read the safety warning page:

Blue light hazard can cause BLINDNESS and not just color perception issues. The power of this laser is no joke, at 1W the Spyder III Pro Arctic is a Class 4 Laser. Do not allow unprotected eye exposure to diffusely scattered light from the beam terminating on a wall, the floor or other flat surface from this laser closer than 3 feet. Accidental eye exposure will definitely result in instant retina tissue damage even within just milliseconds of exposure. Direct eye contact with the beam or reflected will cause instant permanent damage and blindness. Sometimes blindness may take a day or longer for the onset. Unlike instant injury from a bright flash of a red or green laser, this effect is cumulative over 24 hours. It is also possible that such an exposure could cause retinal degeneration and even loss of vision later in life.

Now these things scare the @#$% outta me.

I work around nearly 400 Class IV lasers. How do you think I feel? :)

Actually, we have very strict controls. Each laser is licensed for a particular location. Warning signs/lights/door interlocks, etc are required, as are standard operating procedures and emergency shutdown procedures. We use curtains/barriers/enclosures to reduce exposures. Sometimes we paint the walls and ceiling black to prevent specular reflections.

So far we've only had one person burn their forearm in the 25+ years I've been there.
 
Nah, that's not a laser, THIS is a laser::)

“It's a billion times more intense than any other X-ray source available before,” said Linda Young, director of X-ray science division at Argonne National Laboratory in Illinois, who led the neon experiment.

I worked on many types of moderately high power lasers over the years, but the neatest one has to be the water cooled ruby rod (3/4"x8") and a helical flashlamp that used a dual pulse supply, with hydrogen thyrotrons, that would put a hole in a quarter. Just amazing what this thing would do with a Q Switch.

I just looked at youtube .. man, this is the most popular laser there. Dozens of people have it and made a video. We can expect hundreds of units sold already. Maybe thousands.
How soon will airplanes start to fall from the sky ?
 
Warning!!! Olowkow's link has Avast reporting a virus. It seems to be from an ad on the site so it may not always appear. Proceed with caution.

I just hope those goggles can deal with reflected light.

Seriously, do not **** around with a laser that powerful. I don't think it's possible to overstate how dangerous those things are to human eyes.

The only responsible way to use it is in a light-proof room while everyone present is wearing proper protective goggles specific to the wavelength it uses. If you turn that thing on and it hits a reflective surface you could blind yourself or a bystander for life within a millisecond.

Thanks, I reported my post and asked that the link be deleted.
 
I have several lasers up to 200mw .. but I wont buy this one. Big part of laser fun is showing it to friends. While you can almost safely demonstrate class III laser even without goggles (you just have to be careful not to hit someone's eyes), with class IV you can't do that at all. Diffuse reflection is dangerous. Which limits the demonstration to aiming the laser to the sky. And then you better not live nearby airport, or better, nearby anyone, because 1W laser beam would be visible from all neighborhood.

Anyway I must say that it is one lovely build laser (from what I read). It has special lenses which limits it's power to 5%. It has nice electronic switch which can limit the power to 5% again, and it requires some kind of trick to turn it on (hence kids will not be able to use it), and so on .. I would like to have such features on all my lasers.
 
I consider myself very warned, and will be reading up on laser classes, just to make sure I have not misunderstood something.
 
You guys talked me into ordering one of these 200 mW green lasers. I have my doubts about the power rating as I have seen what appears to be the exact same item advertised as 20, 100, 150, 200 & 300 mW. The price also seems too low. Is there any way to measure the power without special equipment? Or measuring how long it takes to blind me?
I already own a <5 mW green laser pointer that scares me when it hits a reflective surface. I ordered some safety glasses as well.
 
Where from ? Dealextreme ? Their green lasers are cheap for a reason. They have poor build quality, and they do not have IR filter. Power rating is a bit off too, but generally it is in same class as advertised.
Absence of IR filter can be problem. Green lasers work as 3 stage laser, with 2 infrared stages. That light is mostly not focused, but it may vary for each model or even a unit, and it may be dangerous. Also green laser goggles will not protect you from IR light.
So I would recommend finding some cheap web cam, and pry IR filter from it. By this you get 2 things. Camera without IR filter, with which you can check how bad the problem is, and how the IR beams are shaped. And IR filter, which can be easily glued to the device.
Some people say that IR is actually good as it increases burning power. I doubt that, it would have to be focused in same way as main beam. In my experience, IR just make no difference in any aspect, and the problem is not too bad to be dangerous. But as I said .. it may vary for each model.
200mw laser is also a bit strange combination .. too strong to be safely demonstrated .. not that good at burning without focusable head, also 3 stages means extra power consumption (as compared to direct lasers, like red, blue ray, or that 1W arctic). I would recommend 50mw green for beam visibility, and 200mw red for burning.

With a green laser there is a very good chance the power rating is misleading. Green lasers are usually diode-pumped from a strong IR source. Often the residual IR is (1) not fully filtered out and (2) counted in the power figure.

You would be well-advised to confirm the glasses you ordered are both green-safe and infra-red-safe.
 
Thanks Dr. Sid. I purchased through eCrater, it seems like it is coming direct from the Chinese factory, in all likelihood via the back door. If so it might be a reject or may be much more valuable than I'm being charged.
I guess I should have done more research before ordering. All I really want out of it is to do the match lighting stunt a few times if it can manage it. The item listing says it can. If not I'll keep in mind your recommendation of the 200mW red laser.
Good info on the IR. I've got several old webcams I can scavenge from.

jsfisher, the glasses claim they are good for IR as well. Maybe I can use Dr. Sid's idea about the web cam with the filter removed to confirm it.
 
IR filter is sometimes on the sensor itself, but often it is small piece of glass glued to lens, easy to remove. Even with the filter most silicon based cameras can see IR, but you need really everything, because the camera will be blinded by main beam (spot).
That 200mw green I have from dealextreme is bad because it really leaks a lot of IR .. but not so bad, because it is 30 degrees wide cone and it is totally unfocused. You can also judge effectiveness of the IR from the camera (in my case it was almost perfect .. all visible IR gone .. it shows purple-white on the image usually).

If you can cancel your order do so. Peruse the laser forum listed below. Then purchase a laser from these companies *Novalasers. http://www.novalasers.com/.
Other good companies are
LaserGlow http://www.laserglow.com/index.htm and Optotronics http://www.optotronics.com/ppl_product.php
Other companies can be learned of here if the above are not suitable.

* I own one of their Alpha series. Quite happy with it for 2 years now.
 
Each laser can require different protective eyewear. Once the wavelength, power, and few other critical data are known, you can feed the data into software that will tell you what optical density (OD) is required for that specific wavelength.

I'd definitely not be selecting protective eyewear based on claims similar to "good against red lasers". It's simply not that easy.

ETA: I wanted to also say that if a laser is labeled Class I, Class II, or Class 3a, it will generally be eyesafe because your "blink response" will protect you from eye damage in most cases.

The laser stores are all cool but at about 10x the cost of what I ordered I'm afraid those are out of my price range.

I read some of the laserpointerforums site. It was very interesting and somewhat terrifying. I'm definitely going to get some quality eye protection. To be honest I'm regretting my decision to buy. I think this thing will see 2 minutes of use and then get put away in a drawer somewhere without batteries and with a big warning label. That is even assuming I get it. From the laser forum it seems that it will be confiscated by customs if they realize what it is.

I liked one thread on that forum where a guy is asking for safety tips on his first laser, a 5W(not mW) model. It sounded like he had one set up in his basement and people were telling him how dangerous it was but not really discouraging him from using it. It turned out that it was in a lab environment.
 
What I heard, the reason DX does not send lasers to USA is that they often confiscate it. IIRC, lasers are legal in US, but they must have certifications .. which those of DX of course does not have.
I never had problem (Czech Republic, EU) .. it comes in soft envelope, with label 'laser pointer' on it .. wattage and class is only inside on the manual and the device.

To clarify: In the US, lasers are legal to own. Any lasers are legal to operate privately. Public operation is limited, and the responsibility of the operator (mostly, stick with class-III lasers [<5 mW] from a reputable dealer indoors. Never use them outdoors. I do not consider WickedLasers or DX reputable).

Sales and imports of lasers are regulated by the FDA -- that's where non-US sellers often fail and shipments get confiscated by US customs. Mostly missing warning labels on the lasers, or missing safety features on class-IV lasers (>5 mW)

The answer in each case is that they don't, they want them, and a responsible adult will use them responsibly while an irresponsible adult with use them irresponsibly.

People have been using things to hurt each other since the dawn of time. If we are going to start saying things are bad because they could hurt someone, we are not going to have any advances in technology that arn't nerf related.

Lock up those that use it for evil, don't harass those who use it for entertainment. Cops are rather good at finding out who committed a crime. And when the crime is being committed with a giant perfectly straight beam of bright blue light, i think they will find some way to track down the person.

Terrify is one reason you should get a laser that has safety features like a delay on switch.
I've looked a few times I don't see where WL does not deliver this laser to the US.
