My brother came back in town, and we had some fun with my laser and crystal globe last night. It was a lot of fun.

# 3, 4, 5, 6, 11 used the green laser only. I never knew the green laser, when shined through a crystal cube, would turn red.

#1, 4, 5, and 12 are my favorite.

Enjoy

The 4th picture demonstrates it very well: there is something in that glass/crystal cube that fluoresces under green light, resulting in a yellow-looking beam, that exits green, so its not actually converted.

It would be interested to see what that cube does when lit by bluray, could be very pretty.

I have a pinkish marble, and shining a green through it (I don't have it, it was my friend's) made a red line. I was so weird!

Thats fluorescence alright... some materials and dyes will downconvert 532 nm light to yellow, orange or red quite readily. Often those materials react to bluray even more, resulting in a near invisible 405 nm beam going in, but with rather spectacular effects of the beam inside the material... try some things!

And I hope people don't do this with the 445nm diodes without some serious eye protection and all doors to the room locked with a sign on the door etc etc.

I love how some materials do that; I discovered that a dye in my afghan fluoresces bright yellow/orange under 532nm. Discovered it by accident when aligning my Viasho labby.
