Hello all! These seem like great forums!
So, I was wondering if you could lend me a hand. I'm the creater of the 50 dollar laser cutter hack:
instructables.com/id/Laser-cutter-start-slicing-stuff-for-under-50-dol
and I have a question I think someone here knowledgeable in optics and wavelengths can help me with.
In essence it's about frequency absorption. I'm using a 200+ mW red diode to do the cutting right now. My objective material is black construction paper. I have a 3W IR laser diode (fiber optic with no pigtail collimator) and I'm looking into a green laser. So, which will the black paper absorb most of the light from, the red frequency, the green, or the IR? It's black, right, so it should be absorbing all frequency ranges, but I'm sure it makes a difference which laser color?
Thanks for your help, and if you like my project you can send me flowers, diodes, or vote for it so I win the 25W laser cutter here: instructables.com/forum/lamedust---Universal-Laser-Cutter-Finalist/
