How could one go about building an electrolaser? Answered
I know there are a few questions from 5-7 years ago, but they didn't seem to have a definitive answer.
What would be required(financially and knowledge) to build laser induce plasma channel electrolaser? (see: https://en.wikipedia.org/wiki/Electrolaser)
What amount of energy would be required for a small beam to ionize air 15 to 20 feet away?
How could someone build a device like that?
