If you'd like to try it out as well, check out this site.
I was also thinking about trying this, as it's a little quicker, I just don't feel like tracking down the film plates right now. Also, I don't have a laser with a stabilized frequency output, though I do have a couple old cdrom drives...

In the article they use a Class IIIa diode laser with an output of 3 to 4 mW when operated by 3.0 v dc, maybe I could subsitute the cdrom laser (which I believe is a class II) I'll have to do some research...
Anybody know anything about lasers?
Also has anyone tried something like this before?
