>>13746157>isnt this nuclear fission?No, it's purely electromagnetic. Fission is splitting the nucleus, not pulling away the electron shell.
>do you have low power cystals to recommend for this by the way? i think the high power part is because of how durable they are, but ill just be careful with lower power ones, hoping for something near 2 or 3V?
By "high power" they mean high optical intensity (e.g. a laser beam). The crystals themselves are just a medium for optical energy conversion, they don't require additional energy sources to function. Nonlinear optics is notoriously finicky and you'll only get a process to work if you have the exact temperature, wavelength, phase matching angle, etc.
If you actually want to mess around with this stuff I would strongly recommend working through an entire textbook on the subject first because optics aren't cheap and if you don't know what you're doing you're just burning money.
