I found this really good write up on Kerr Cells "kerr_cell.pdf"
I think Kerr cells are basically an early version of an LCD. So you could probably make a Kerr cell by filling it with LCD fluid. You can probably get fluid from a trashed LCD display. This would give you a non explosive version.

Yes that's a good PDF Keith the fluid you could experiment with it would work to some degree with different chemicals the first Kerr just used lead Glass perhaps a copy of the Faraday light valve.
I for sure agree any hobby experiments with this idea should use some thing safer than Nitro Benzene ,the good thing with the device is all you have to do using a liquid is pour it out and try another .
I have never really thought about trying one due to the chemical used or a need one as we all use LED'S these days but it is interesting and does have the option of using any type of light .
I don't know of the LCD fluid from a projector is it ? i have not had a chance to scrape one to see what goodies are inside ,sounds like it would have enough ? .
I am just thinking about it at the moment toying with the idea what would be needed to try one if it ever happens .
A vessel of some sort
Prisms i am not sure i have at any great size ,rather track down the polarized lenses this is what would make it workable idea ,have to have a look if i still have them.
Reading up there seems to be no set KV voltage for these due to the different sizes so better to much than not enough ,i think mine can do 10 to 20 KV
would be good to make the EHT supply variable .
I will have a look what i can find laying around it would be a bit of a knock up if it happens ....i would be very interested if others had a go at one as well just for the hell of it ..
The electromagnetic spectrum has no theoretical limit at either end. If all the mass/energy in the Universe is considered a 'limit', then that would be the only real theoretical limit to the maximum frequency attainable.
