An electrical charged particle can be accelerated to a electrical potential difference.

But how do you accelerate a particle using the laser?

I'm not talking about - Laser-driven acceleration of neutral particles.

I found articles where you can accelerate particles using the laser.

Laser-Plasma Accelerators - Is again an interesting subject.
I have not been able to understand it unfortunately...........

I would like to see something practical, that until I can see how it works I do not get it right.

Are there experiments that can be made diy?
Or do some institutions have open gates to see something like that?

It's unlikely you will see practical Laser-Plasma devices soon but RF Linac systems are common in science & industry and operate on the same basic principle of phase synchronizing electric fields to moving charged particles and reducing the electric field when it 'pushes' in the wrong direction.

Even the cathode tube It has a particle accelerator. Particles are obvious electrons..............
Do not think at CERN where more countries joined together to build such a thing.

I think simple.....
I can use a laser toy (a laser pointer) to create an electrical potential difference at the ends of a material that I can measure ?

New discovery could enable portable particle accelerators

Could Enable Portable Particle Accelerators

I'm not saying this is true!
I'm just saying it's possible to be true.
And they are reserved, I use the word "Could".

I want to discuss how it Works, to infer the chances that such an accelerator will appear in the future.

This device looks to be a low power pulse system. I would suspect for most practical applications it won't be very portable.

"For example, an experimental laser plasma accelerator at Lawrence Berkeley National Laboratory accelerates electrons to 1 GeV over about 3.3 cm"

"A proof-of-principle plasma wakefield accelerator experiment using a 400 GeV proton beam from the Super Proton Synchrotron is currently under construction at CERN.[9] The experiment, named AWAKE, is scheduled for start-up at the end of 2016"
https://en.wikipedia.org/wiki/AWAKE

So they use protons coming from a synchrotron. 400GeV. They want to get accelerated electrons with them........Sound stupid. I'm wrong? For what can you use that?

The best way to understand how it works is to work in that field.
I applied to CERN. But I did not succeed because I did not have 2 recommendations.
