Have you even looked at the pictures that have been posted of the glasses? They have an OD rating on them, they also appear to have glass lenses, you're not going to burn a hole in them.

They're not glass. A pair of 350-550nm glass filter-equipped goggles (I believe that's the range, not the point here though) costs well over $100 a pair, WL wouldn't spend that kind of money on goggles to include with the laser.

They are a Chinese company :p

Thank you for posting on here and asking for ideas.

There is one thing I would really like to know, and I'm sure others would too. After your tests are completed, test the lasers waterproofness in a bucket of water or something similar for a length of time. I have read it is waterproof up to 20m for hours from an email from wicked to another member. I'm curious if this is true, waterproofness is a huge selling point for any laser / flashlight for me.

Thank you.

I'm curious if it will "Blend" . . .

Well, yes, it will burn through tin foil, in a way, a 455nm at around 900mW will go incredible fast through a Hersey's new foil wrapper and start melting the chocolate and then burn it.

Yes too to boiling water, also, in a way. Get a glass of water, focus the beam at the top of the water, right at the meniscus that forms on contact with the inside of the glass. You will start hearing a crackling noise of the water boiling, very interesting sound. It is boiling just in that area, not the whole glass.

Yes also to the magnesium too, but you just need to use a small amount of metal filings or powder (powder goes off really fast, so be very careful, use eye protection, the spark is very bright and blinding) 8^(

Yeap, been there, done that... I am away from home and from my lasers, otherwise I would have prepared some quick video. :D

@Jon,

I also agree on doing for the power vs time, you will see how fast the power start drifting down. I am not sure what Wicked is using as their driver, but my quick tests with my new Kenometer (Laser Power Meter) shows the power steadily going down. Right now, I am not sure if it is the battery, the driver, or the laser diode that is causing the drift.

Also already mentioned is the divergence and that the laser beam is not round nor it travels a long distance without expanding its diameter. That is important because people will be expecting to get a nice round dot which will travel a very long distance expecting to see a small dot miles away… that is not the case with this one. I have not received my wicked laser, but from initial comments here, it is not round and the divergence is greater than specified.

Another suggestion is to do show how bright a fluorescent marker becomes when illuminated by the beam of a 445nm. The point here is that the human eye cannot really see how powerful these lasers are, we can only see less than 1% of the luminosity, compared with the peak at 552nm (100%). So when the marker is hit by the laser it looks extremely bright and capable of flooding a room with a yellow-green light. (Make sure you are protected from reflections, safety glasses is a must)

Another “test” is to show how fast it burns through a regular ice cream bar wood stick. I will create a whole in less than 30 seconds.

Finally, love Maximum PC! :D

Since you will be taking that laser to the Lawrence Berkeley Laboratories, the test I would love to see confirmed is related with the single mode at 224mA (about 54mW) and around 400mA (about 200mW):

445nm diode info

445nm laser diode

W’s Laserblog

100mW+ single mode external cavity diode lasers (ECDL)

and others.

The existance of the single mode means that it has only one single wavelenght. These lasers are multimode when they are run at higher currents.

If the single mode is there, at what currents and temperatures ranges is it available? What is its coherence? Under those conditions, would this laser be capable of being used to create holograms?

Thanks!

Did you get the expanded lens kit by chance?

I was wondering what the power readings would be using the flashlight effect lens and Floodlight Effect Lens, at maybe 20-40 ft out.

The power will be the same but spread out over a much larger area.

I will second the earlier suggestion of a plot of power over time but just stipulate OPTICAL power.

I am curious to know what kind of fluctuations in optical power (if any) occur over 1 to 5 minutes.
I've had a couple of DPSS 532 nm lasers that just jumped around on their light output and it was rather annoying.

Thanks,

-Scott

Welcome! Thank you, for giving us techies a heads-up to a kewl new magazine! I'm always looking for leading edge tech publications on the news stand before gulping down my Starbucks espresso laden drink.

Try to obtain a cow's eyeball and slice it carefully at the back and install your laser power meter to get a reading as the beam enters the eyeball gelatin. Another experiment is to install a thermocouple into another eyeball and graph the temperature over a 30 second exposure. And lastly a macro video footage of a head-on 30 second exposure to a cow's eyeball, and posted on Youtube.

That one is to be displayed in your Maximum Tech magazine( a few frames), to warn of the danger associated with this laser, for the unknowing public. I mean if that appeals to you of course, it's your choice. Don't forget to put pics in the magazine showing the beam bounced off of a few mirrors with a little smoke. That always looks good.

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