Thank you. I'm trying to make small (nm length) "chains" of ions to see what the effects are under different conditions. This is a little outside the bounds of the laser forum, but since a laser would be making positive ions by stripping the electrons, could a focused electron beam be used to...

Adding or removing electrons from an atom, ion, or molecule to create a net charge. Just because you ionize something doesn't mean it has to go immediately back to neutral and release another photon. I guess I should also ask, does the electron have to be completely stripped off of an atom or...

Hey everyone, I'm trying to build a setup that would allow me to ionize air along the beam path by sweeping the focus in and out. I need a laser that can be turned on and off rapidly (nanosecond scale) without breaking while also having enough power in each pulse to ionize the air. I'd like to...
