What's a collimation point? I suppose I could insert an absorptive collimator after the collimating lens to further clean up the beam if necessary, and if really really necessary split and prefocus the different wavelengths or filter them out completely...

Well, good thing I intend to try ;D I considered doing it with a classical crystal engraving machine, but doing what I want to do requires a significantly higher load on the machine than doing graphics (they only insert tiny dots, I need to remove material.) Additionally, the workflow and the...

1x large collimating lens 1x large, maybe fresnel, focusing lens 100x (hyperbole, or is it?) diode focusing lens, maybe fiber optic kits, heat buffers 1x mounting scaffold could get tight.

I'm trying to etch microchannels into the plastic to serve as a delivery and mixing method for a "lab on a chip" type thing. i'd say the maximum budget is $1000, but I'd much rather do it for 100 I hope that I don't need to carbonize (split up the molecules) to achieve my result. And foaming...

Yeah I've been on his site yesterday I think. it looks like it hasn't been updated since 1999, so I didn't write him yet. (although this seems to be a common theme in the laser community, no offense pls :D) but I don't want to engrave glass. I want to use a really wide beam angle (up to 45-50°...

Hi! The thing is, I don't actually need to break down the molecular structure with the laser alone. Evaporating or burning it should be enough. If you are concerned about the fact that even a powerful laser is not very efficient (because well, the work piece is transparent) for a proof of...

Not really, but close. :crackup: Hi! I am attempting to construct a so called "Sub Surface Laser Engraving" (world famous for shitty monochromatic 3d pointillism) prototype machine for plastics and call it "Sub Surface Laser Beam Micro Machining". and I am here specifically to rake in all...
