Analysis of fast MOSFET based High voltage switch for High Voltage Electro-Optic Devices is presented. Single MOSFET connection is considered by using Laplace transformation. Based on executed mathematical transforms, directions of improvement ways for typical engineering solutions are analyzed. Improvement directions including fastest operation, optical losses minimization, optical behaviors improvement, cost reducing, size and weight decreasing are considered. Modern Optical Arrangements of an Electro-Optic Shutter Schematic are compared. Different schematic designs of Q-Switch Drivers for Pockels Cell are presented. Parameters of constructed based on presented analysis Q-Switch Driver are given.
