UNPOLARISED ELECTRO-OPTICALLY Q-SWITCHED LASER

摘要

An unpolarised electro-optically Q-switched laser using a laser rod, a prism and a Pockels cell between a pair of mirrors wherein the prism is selected to give a low-angle walk-off arranged that when a quarter wave length voltage is applied to the Pockels cell the first pass will be cancelled by an equal and opposite walk-off during the return path.
