There are submicrosecond level shifters such as this:
https://www.onsemi.com/pdf/datasheet/mc14504b-d.pdf, and if the impedance
was high enough on the input you could even use a high side driver for even
faster switching speeds.  However, if you are driving a Pockels cell (which
normally requires analog instead of digital control) I would just use an
op-amp voltage multiplier.  A unity gain stable op-amp would be the easiest
bet, and one like this would be plenty fast:
