REALLY cool 532nm fluorescence (not the norm)

Ok, so I went to visit my mom earlier this week, and she showed me this new ring that she had a local jeweler make. The blue stone is a giant blue sapphire surrounded by diamonds. She is saying the ring should appraise somewhere over $10k :eek: :eek: :eek: :eek:

Anyway, I happened to have my x-series with me in my pocket, so I tried shining it through the blue stone. I was shocked to see the beam turn bright RED. This was like 660nm really deep red, not the bright orange which 532nm normally fluoresces.

Anyway... here is a picture of the ring before hitting it with the laser:

and here is the fluorescence!

I thought it was pretty cool!!!


Here are a few other random pictures I took that day:

x-"75" (peaks close to 135... averages like 115-120)

And a couple random pictures of my doggie... hehe.

Very cool. Does the beam leave in red too?
The deepest red I've seen so far is olive oil, that's brownish red.
Fluorescence is always broadband, so if you say it is deep red, than most of the light is in infrared.

Awesome!
Yea, I just started finding lots of things that fluoresce to 532nm, but none fluoresce a deep red! (Some do fluoresce a bright red, though)

Your dog looks exactly like my uncle's dog - but only his dog had one blue and one brown eye. BTW, your dog looks kinda scary with the red eyeshine!

I get the exact same fluorescence with one (only one) of my optical calcite samples... I've been trying to get one of my optics professors to tell me what impurity causes it. I haven't tried it with my 532's from Nova yet so I originally wondered if the fluorescence was caused by some IR in my cheap <5mW green pointer... :)

Try it with a violet lazser, or otherwise a regular UV led or blacklight tube

Awesome! Yea, both dog and ring ;D

Funny, olive oil always gave me orange fluorescence. :-/

All 532's are the same when it comes to wavelength I believe.Fluorescence from IR cannot be in the visible spectrum. ::)

Cute dog, looks like he's protecting a vampire during the day with the red eyes!  :p

Just out of curiosity, I was wondering about that rings fluorescing..

I have some material that fluoresces 532 light (who doesn't) but one of this cloth I have is pink/orange/reddish color that makes the light turn bright red not deep red.

But could it by IR?  I know the CNI's have filters, but some leak through right?  Try it next time with some distance between the aperture and the stone, see if it makes a difference, although Switch said IR doesn't fluoresces in the visible spectrum. :-? Well what about the chemical compounds that make up the stone?  What if it isn't fluorescing, but actually changing the frequency just like the crystals inside the laser?  Either way, is it possible that it's the IR leaking?  Or is it solely the green light?
