Nowadays there is a wide use of electro-optic (EO) sensors such as in sighting and observation devices. Starting with the innovation of the laser at the beginning of twenty century, laser sources have developed to be compact and more powerful. High Energy Laser can perform hard or soft damage of electro-optic sensors. In this thesis, the dazzling and soft damage of the electro-optical imaging sensors like Charge-coupled devices (CCD) image sensors and Complementary Metal Oxide Semiconductor (CMOS) was studied both theoretically and experimentally. A MATLAB simulation module is built and used for predicting the design parameters of practical laser system capable of damage EO sensors from short distances in laboratory scale to different propagation distances outside the laboratory by maximizing the laser pulse energy. In addition, we presented and implemented an enhanced high energy flash lamp pulsed Nd:YAG laser system based on master oscillator power amplifier (MOPA), the configuration consists of one master oscillator with output power of 330 mJ followed by two amplifier stages to amplify the master oscillator power to (2J) to achieve the soft damage effect of numerous types of EO sensors at different distances. The simulated and measured parameters of the output energy show a good agreement. Finally, charge-coupled devices (CCD) image sensors are successfully damaged at a distance of 4 Km. The study showed a good agreement between the theoretical and experimental results
