How to make laser-induced plasma? Answered

Hi, I was wondering how I could possibly make a small version of laser-induced plasma. I understand there would probably be high voltage as well as precise electronics required, but I'm quite confused by what I've found online. I would just like a simple explanation and/or a theory. Thanks!

Cheers,

Any strong CO2 laser can ionize the constituents of air.

Ionized gas is not a solid 1, not a liquid 2, not a gas 3 but it is a charged atomic cloud capable of conducting electric current, that is a plasma 4th state of matter.

Fluorescent lamps are plasma devices. Scientists have ionized air to help direct lightning charge to follow the a laser beam towards a solid metal conductor.

watch some youtube about plasma cutters, it might inspire you.

(continuous spark + compressed air jet= plasma that can cut through metal)

Iv got one ,they can be fun,

as for making a lazer plasma thingy,i wouldnt know where to start.

You need it for spectroscopy, as an electron microscope or as a directed nergy weapon?
Well, in any case if you fail to understand the priciples I see little to no chance that you can build one.
After all research sections of very large companies waste millions on a working prototype....
