Why not just use a laser? I vaporize rock instantly with an 80w CO2. vacuum the dust up and blow it out the other end, done. Throw it on a galvo, you can control where it aims and fires.
- HPsquared 2y agoI don't know much about lasers, but this seems a very "dirty" environment for that sort of thing. Wouldn't the lenses etc get all fouled up?
- mcswell 2y agoDust? Vaporized rock going through a vacuum is not going to be kind to the inside of that vacuum.
- lightedman 2y agoYes, this is a known thing to anyone that does stone engraving for a hobby. Those are then considered consumable parts in the operation.
- avsteele 2y agoyour beam waist is going to increase (and intensity is going to drop) after a few hundred meters. you'd have to lower the whole laser down the hole
- bilsbie 2y agoMaybe use adjustable lenses?
- lightedman 2y agoThat's what adjustable diopters are for. Also, at certain power levels, the beam is self-focusing.
