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!

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.

Not sure which laser induced plasma thingy you want. Asking Wikipedia about that phrase gives this list of existing articles,


I am guessing you want either the spectroscopy method,


or the Electrolaser ray gun thing,


Or maybe you're looking for something different?

Cheers to you too,

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....
