# What are we working with?

- CO2 IR lasers (~10,000 nm) are pretty common; local hackerspace has an [80W Trotec Speedy 300](https://wiki.fatcatfablab.org/wiki/Laser_Cutting)
- More recently higher power fiber (NIR 1064 nm) and diode (visible blue, 455 nm) based machines have become available. One particularly nice one is the [XTool F1 Ultra](https://www.xtool.com/products/xtool-f1-ultra-20w-fiber-diode-dual-laser-engraver) which has 20W on both of these wavelengths. Also neat is that the laser is moved by galvanometer, potentially allowing us to have higher resolution patterning.

(I learned about the F1 Ultra from a recent description of [how to make surface mount PCBs on the laser](https://github.com/sphawes/fiber-laser-pcb-fab) corresponding [youtube video](https://www.youtube.com/watch?v=wAiGCyZZq6w))
