What I'm thinking is that cheap semiconductor lasers ought to be able
to cut through thin plastic like this any day now. There are already
100 watt CW single-chip lasers around. That would be slick.

The yags and CO2's they use for bowling trophies and laser trimming
are still big and expensive.

Why don't you buy a cheapie Chinese 40W CO2 laser and give it to your
folks to play with?


Got any leads to them?

John

There are some eBay vendors with complete x-y devices for about $1300
delivered (but reportedly with horrific copy-protected software).

Might be easier to adapt that and just hook into the XY steppers. I
think they move a mirror (prism?) or two and the laser tube itself
stays fixed.
