@519asdf Not really, but it IS special paper... really it is vinyl... you can order it through educational catalogs, etc...

Dr. Carlson,
Ive just discovered your videos today, and although some of them are a bit simplistic, your demonstrations really are amazing. You've done an excellent job at targeting both younger viewers and college students alike.
Now, I hate to quibble, but wouldn't two photon absorption contradict your statement near the end of the video?

@grazingkow Not sure which statement you mean, but you are correct in that I have totally ignored two photon absorption in my explanations for this video. On the other hand, two photon absorption occurances are fairly rare...

@sciencetheater My advisor did his dissertation on two photon lithography, and when he explained how all that worked to me, my mind was blown.
Are you still creating these videos, or it this just a cache of your previous work?
grazingkow 1 year ago
@grazingkow I have a dozen or so videos filmed that need to be edited, but a sabbatical out of the country and a new son have kept me from posting anything new in nearly a year.
Hopefully more videos will be posted soon...
