Harnessing Plasma with a Laser Pointer and Nitrogen

[Hxopblxvj]

I was wondering if I could create plasma inside my own apparatus using a laser pointer and nitrogen..

I doubt it; the laser intensity is not high enough.

Well, how can I make plasma

Apply a very high voltage between two plates.

If in dry air/nitrogen, 20,000 volts per cm should generate plasma. You can run the voltage up and down to get corona, arcs, or sparks.

Or you can just buy (a) a plasma ball, or (b) a plasma furnace.

Depends on what you are trying to do with the plasma. I once say a plasma incinerator at a high school science fair - the boy made it in the garage; his parents had no idea what he was doing! It was pretty impressive.

Also very dangerous, but he was very careful, and followed good design principles.

Thanks for the info. Ultra, I appreciate it
