ABSTRACT:
A controllable ultrafast light shutter utilizes two sets of Pockels cell-polarizer combinations, one set is used to open the light switch, the other to close the switch allowing the selection of laser pulse duration in the picosecond region. The opening and closing of light switches thus operates as a light shutter.
