Testing Wicked Laser Arctic in laser lab 08/02/10; your requests are welcome

About the "will it blend" question ..... why you don't just write to BlendTec and ask them ?

After all, they buyed iphones and ipads just for blend them, an Arctic must not be a big expense, for them ..... :eg: :eg: :eg: :eg: :eg:

:crackup:
 





Thanks for all the suggestions and nice welcomes, everyone. There's almost too much to respond to here (especially without going back and rereading every comment), but I will share the following:
- Hi Derek! (And Dave and Sam!)
- Our supplied goggles have plastic lenses.
- We did not receive the extended lens kit, and we don't have a focus lens. There are both good and bad points to this. On the plus side, we will be evaluating the "basic" Arctic experience -- what the average know-nothing Joe receives when he orders the laser just because he's read all the hype. On the down side, we won't have the focus lens to determine best-scenario burning capabilities.
- It may be hard to test divergence at large distances at LBL. I don't know the layout of their lab. But we can do this on our own at some point.
- We will certainly test power fluctuations over time.
- The cow's eyeball experiment is an interesting one, though I'm not sure we'll have time to get the eyeball before Monday, or even have enough time at LBL to get to that kind of test. But at any rate, it could be a vivid demonstration of how dangerous the laser is. Now, that said, we don't want people to ONLY be worried about their eyeballs melting. Blindness or loss of green perception almost certainly happens before much obvious physical damage occurs (right?). Nonetheless, your proposed experiment still uses great theatrics to teach an important lesson.

Hey, on the subject of mirrors: We're planning on a mirror set-up for the shoot we're doing in our studio (we already have smoke and dry ice too). Can anyone point me to on an online how-to article on the quickest/coolest way to set up a mirror arrangement? This could save a lot of precious time in the studio. Also, I am concerned about the beams reflecting onto random surfaces inside the studio. My plan was to start the set-up with some low-powered laser pointers (just to establish placement of all physical elements) and then sub in the Arctics once the setup was refined. But are there like "known arrangements" for creating spectacular crossed-beam scenarios? We will have six of these mirrors total: Large Front Surface Mirror (Square) 100mm - Optics - Novalasers Inc.

Thanks again, everyone. VERY much appreciated. Good comments and suggestions.
 
Beam Profile would be the most important I could think of.

I recently did it in a lab with a the scanning knife-edge technique, but you may not have those resources. That would allow you to find the divergence, beam diameter at any point, and beam quality (m^2).

Or you could just buy a beam profiler.

Distance doesn't matter. I completed my experiment over the distance of about 20 inches, and that was with a very low divergent Helium-Neon laser.

You just need to be sure that you take your beam diameter measurements a good distance past the beam waist (focal point). You want to be taking your measurements past the Rayleigh Range (where the beam diverges linearly thusforth), if you don't do that, then you will be finding divergence when the beam is still diverging exponentially.

If you are able to test the wavelength on a spectrometer, would be great.

I second it, it should show the multiple peaks (multimode mode) and that is not a "pure" laser, a laser with a single wavelength.

Hi Jon :P I am very excited for your review!!!
 
When working with many mirrors, try to keep the work surface at waist level, keep all mirrors reflecting on the same plane, meaning they must all be perpendicular to the ground. This will minimize the chance of laser being redirected up or down.

if you have a low/high mode laser, you can try fluorescing different things for some neat shots.

for a focus lens, you can add another coated collimating lens to focus it down to a point, or - if everybody has eye protection - you could probably get away with using a magnifying glass.

I think the biggest thing people are wondering is the actual power output. And I don't think the blend comments are serious.
 
Hopefully this review will come out soon. I think it will clear up a great many questions by those that have yet to received their laser.
 
I got my mirrors from a laser printer assembly and cut them down. Once I had them cut down, I then glued them to a base unit that could be moved around. I recommend getting your mirrors from a cheaper place though.

there are a ton of mirrors there that will suffice for what you want to do.

If you are gong to do mirror work, remember that you will need front (or first) surface mirrors. "Normal" mirrors give you a double reflection.

Peace,
