Hello, I wish to switch ON and OFF a high-voltage (that generates a high electric field) using a ultra-fast laser as a trigger. Basically I have a flow of charged particles that I want to quickly deflect using an E-field. The timing must be correct and controlled by a LASER. Does anyone know some way to achieve this scheme? I know there are some pretty fast pulsed laser (picosecond? nanosecond?) can these frequencies "tranduce" a high voltage? Is there an intrinsic upper limit in term of frequency for the High-voltage switch? Help will be much appreciated.
