Would it be possible to laser ablate a Silicon Wafer on the laser tools? What is the smallest size the laser can scribe?
Doubtful. Si has very low absorption at 10u, and also good thermal conductivity. SiO2 on the other hand…
Our smallest size would probably be 4 to 5 orders of magnitude larger than CPU chips.

thats ok, do you have a rough idea how large a spot the laser can cut? Is Silicon possible on the laser?
You are better off with a YAG. That is what we do in the industry. Be ready to handle the slag…huge issue. When we dice at work we use a photoresists protective coat.
