Thanks for the correction = =, I think I misread the Wikipedia description. Hmm, is there a laser that emits electron like an electron microscope? And is there any application for it? 1 hour ago, Ghideon said: A free electron laser employs electrons as a gain medium. Photons are emitted, not electrons. edit: x-post I see, good call.

As far as I know a laser is a device that emits light. Maybe you are looking for electron emitter such as those used in cathode ray tubes? Link to comment Share on other sites More sharing options...

What electrons? Free electrons in the air between the source and the target? Link to comment Share on other sites More sharing options...

Yes, electrons created from air plasma that would flow along the laser's path. Link to comment Share on other sites More sharing options...

You went from “would they flow?” to “they will flow” Pick one. If it’s the latter, you need to explain why. Link to comment Share on other sites More sharing options...

Also has to worry about wavelength because if it is too small it might not work. Edited May 19, 2021 by fredreload Link to comment Share on other sites More sharing options...

Moderator Note The electric and magnetic fields are transverse to the direction of the light’s path. I’m not inclined for you to make another half-assed guess. This doesn’t meet the standard for rigor of speculations. We’re done here Link to comment Share on other sites More sharing options...
