i included in the post.
I’ve made CO₂ laser mirror targets:
The black layer is either present or ablated away, so it doesn’t provide much information on the energy distribution across the beam and I cannot retire my manila paper targets.
Tiny test patterns showing mechanical wobble:
Those are 1.5 mm circles inside a 10 mm OD outer circle.
And some nice plant tags:
As I said in that post: “my fascination with this paper boils down to it’s cheaper than Trolase for applications not requiring archival quality and duration”.
