mW is a milliwatt, or a thousandth of a watt. 1000 mW = 1W.

thanks, that what I though but also thought that CAN"T be true. I probably should not have ordered this now that I realize its full power. I got to say I hope this shut this down. It is a little scary.

Re: Wicked Lasers 445nm 1W(!) portable deathray
Nova's site notes that the 1W laser can inscribe wood; definitely something one of you early adopters should test. Some other ideas aside from cutting a block of dry ice:
- See if it can boil water in a shot glass
- See if it can bore into and disable an inflated car tire
- Point it at a glow-in-the-dark object nearly long enough to burn it, then measure how long it glows
I'm also wondering about low-orbit applications; if, on a clear night, you pointed this laser at the International Space Station (~200 miles away, but only ~70 miles contain air), would they be able to see it? Is this the moment any common person can buy a single light source visible from space?

Re: Wicked Lasers 445nm 1W(!) portable deathray
I like math, so let's see if I still remember how to do it. Let's assume the atmosphere has no effect on the beam. With that assumption, we've got, essentially, a cone diverging at 1.5 milliradians and going for 200 miles. I get a circle with a radius of about 1600 feet up at the ISS height, or 1 watt per 1970110 square feet. That kind of spread seems to indicate that it would not be dramatically visible at that range. It's 0.000000508 waats per square foot.

Re: Wicked Lasers 445nm 1W(!) portable deathray
Fair enough, but can you see a 0.000000508 watt per square foot light source against a completely black background, like a rural area on the night side of Earth?

Re: Wicked Lasers 445nm 1W(!) portable deathray
I dunno. That's a lower surface brightness than the dimmest a T1A Titan will go. I did the math mainly to be sure that nobody would be blinding our astronauts!
Edit: 0.000000508 watts per square foot works out to about that energy divided among 40,000 1.5mm-size sources due to the die size. So you'd be looking at, from the ISS, a 1.5mm object with a surface brightness of: 5.08*10^-7 divided by 40000 times 100 (lumens per watt) lumens. That's really tiny, something like a billionth of a lumen. Maybe I'm taking the math too far? It would be a very dim, striking blue point.

Re: Wicked Lasers 445nm 1W(!) portable deathray
Hm, that's very dim, but if it were all in a tiny point, I'd say that's a "just maybe".
It just fascinates me to think that last month, the idea of someone owning a light source visible from space would be ridiculous, and this month you can do it for ~$200..

Re: Wicked Lasers 445nm 1W(!) portable deathray
Note: I could be doing the maths wrong.
Oh, I just remembered the other math to do. The human eye has trouble resolving tiny details - anything smaller than a certain angle will appear to be a dot. At 200 miles, a 1.5mm object is .000000233 degrees of arc. 20/20 vision can resolve detail of 1 arc-minute, and anything smaller will appear to be a perfect point. The laser's aperture at 200 miles would be about 150000 times smaller than the ability of human vision to resolve distinct objects. So given that the laser's brightness would not be much greater than a black background, and its tiny apparent size, I doubt that it would be particularly visible at 200 miles. Maybe on a perfectly clear pitch-dark night with no other light sources around and our spaceman has completely night-adapted vision.

Re: Wicked Lasers 445nm 1W(!) portable deathray
I have an 885mW laser I made from a 12X blu-ray drive.
It burns you, but if you sweep it across your skin at a little more than an inch per second, you won't really feel it much more than a warmth. It's when you stop moving that it quickly burns. If you set it on a table, it will burn your hand from 25 feet away if you stop in the beam.
These 445nm Casio diodes can be driven at much more than a watt. So far they have been tested at 1.5W and more. I have one showing up tomorrow.

Re: Wicked Lasers 445nm 1W(!) portable deathray
lol, good one
I still think that's promising; I wonder if a 1W green would fare better? Did we resolve if the same wattage of different wavelengths make a difference?
Feel free to post burn test results/pics/videos, we're ready to see what it can do..

Re: Wicked Lasers 445nm 1W(!) portable deathray
if this is really 1 watt and not an other underpowered piece of crap from wicked lasers i'm definitely getting one.
Looks like NOVA lasers is making one too!! their product is usually much better and OVERpowered!
http://www.novalasers.com/NOVAstore/pc/viewCategories.asp?idCategory=2
other forums are reporting a 200 dollar pricetag as well!
ugly though

Re: Wicked Lasers 445nm 1W(!) portable deathray
So you're cutting the laser intensity to one 38.6 billionth of its intensity, and it's probably at a size that your eyes just can't see unless it's rather brighter than the background. I suppose we'll hear from NASA soon enough, right?
I don't know the optics to calculate wavelength comparisons. There just isnt' enough power going to the right places. It just needs better collimation. Our spaceman is really only going to see something like a billionth of a lumen's worth of light. One way to look at is is to divide the apparent brightness of the laser among the area the laser will occupy at 200 miles - the laser will be spread across 197000 square feet, and the diode was originally 7.607756x10^-5 square feet.

Re: Wicked Lasers 445nm 1W(!) portable deathray
That'd be a pain to actually try to carry out the experiment - you'd need to mount the laser to one of those computerized telescopes that follows objects in the sky (and I don't know if they can follow low-orbit objects), and figure out some way to aim it..
Yup, it's not on the site anymore, Google search just directs you to the dead page. I wonder what that's about..

Re: Wicked Lasers 445nm 1W(!) portable deathray
I call complete BS.
Burn flesh? No.
Burn bugs? No.
Burn or pop a car tire? No.
Boil a shot glass of water? No.
Pop a balloon? Black only, motionless, projecting the beam at exactly the same spot for a minute, maybe.
Cause blindness? Can't any $5 department store laser do that, or for that matter a cheap flashlight held to the eye? Isn't it just a function of how long it takes?
