Wanting to make a CNC Laser, I needed to know what the ablation wavelength of Copper (Cu) is, now sure I asked and was pointed towards a CO2 laser which has a wavelength of 10.5um granted just about EVERYTHING absorbs that, but until I actually got one and in the price/size/power range I wanted, I wanted to see what other wavelengths could be used for other ablation purposes, so I set out to start finding that info.
Low and behold I found:
NIST: Basic Atomic Spectroscopic Data - Perodic Table
which has a periodic table that you click and it takes you the basic data, but for our purposes if you click on strong lines (right next to to atomic data) it lists the ablation (absorption) wavelength of the material, so for the example of Cu it starts to oblate at 2000nm in air.
Wanted to at least attempt to contribute to the community rather then just take from it, so enjoy, I'm still trying to locate a list of more common things or of compounds like plastics or plastics of a certain color, or other common materials.
