ENERGY EXTRACTION OF PORRO RESONATOR IN POCKELS CELL Q-SWITCH OPERATION

Deviation of a practical Pockels cell Q-switch bias voltage from the i deal bias value significantly affects the extraction of useful output energy. The losses of two practical bias voltages are calculated and t he properly rotated angle towards the right-hand side prism of the Por ro resonator is determined to simulate the different losses. The losse s are due to deviation of the Q-switch bias voltage from the ideal val ue. It not only degrades the useful output energy, but introduces a us eless energy loss in the reverse output direction. For the different l osses of these two practical Pockels cell bias voltages, the useful ou tput energy difference is about 30%. The useful output energy and lost energy ratios of the two equivalent loss configurations are 0.54 and 0.89, respectively. These ratios agreed quite well with the theoretica l results.
