[CLOSED] Guess what laser is this. - It's a PHR-803T.

[Johnyz]

It is REALLY foggy today, so I thought it would be nice to do some beamshotting. The photo that came out was so... unique. Now, I'm only gonna tell you one thing: it is NOT PHOTOSHOPPED. I know it looks like, but it really isn't. Now go ahead and guess what laser is this.

And the results are in. 3zuli got it right almost immediately, it was a PHR-803T at 100 milliamps. I know it's unbelievable, I will post photos of it if you want me to.

Explanation: I was very surprised too, here's why it looks like that.
1) Extreme fog - it was probably the foggiest day I've seen last 3 years.
2) Long time exposure - it was a 4 seconds exposure photo.
3) Bad white balance - because of that strange street lamp behind the house.

Looks like everybodys favorite nichia diode to me.

phr-803t / 405nm

Looks like a 405nm laser.

LOL, also 405 posts.

Im going to guess its some type of a blue DPSS.

Re: Guess what laser is this.

405nm would come out more violetish in the picture.

I'll guess 445nm diode, powered normally. I've had fog dense as milk once, Arctic's dot on a building 35 meters away was barely visible. Beam though... :na:

Kind if similar to what you're getting.

Nice picture, also!

Divergence appears to be typical for a 445..

447.23nM :shhh:

Multi-Line Argon.

I'm going to say that the camera apparently screwed up white balance because of that strange lamp that's behind the house being lased, so the photo is more blue than it looks.

Looks like 445 to me...

WL Arctic.

Re: Guess what laser is this.

Another thing: rayleigh scattering did its job, the beam is much more fatter in the photo than it actually is.

So nobody got it right so far? :thinking:
The suspense is killing me....
