OK fired the BR at a mirror in the dark and noticed where the beam strikes the mirror it leaves a spooky red flame-like trail when you move the BR dot around!

You know what they say, small things.......
 





Can you shine it at the back of the mirror? It looks like it might also be the coating glowing because of light that passes the aluminum vapor coating.
 
and you're sure this is not in your eyes???
are you sure its a glass mirror???
have you tried different mirrors in the dark with the same result??
 
yes it's the mirror. Every mirror I've tried my blu-rays on do the same thing, some have a bigger tail than others though. Pretty neat!
 
OMG it's glass related, just tried it on my frosted glass desk and I can see that trail!!!!
 
So it's the glass not the metal coating. :P I thought it was awesome, but I couldn't get it to show because I was moving the laser too fast at first. :D
 
It looks pretty damned cool!
I can see it on many mirrors around the house, as someone said on some more and on some less.
Can´t see it on my frosted glass tables, though. :'(

And I noticed that it fades/stops, as soon as you switch of you laser.
What is it? If it was fluoroscence, it would not 'trail' at all.

It is a combination of fluorescence and phosphorescence.

Peace,

It pretty cool, I doubt it would be visible on camera though.I would like to see this through 405nm goggles. 8-)
 
Possibly has something to do with color centers from either imperfections in the lattice structure or impurities that demonstrate electron traps with long time constants.
