We report on the application of new electro-optic modulators which are controlled by photoconductive switches. Various configurations of modulator are presented and are applied to several applications. Experimental results are presented in which a photoconductively controlled modulator is used to Q-switch and cavity dump a Nd:YAG laser, utilizing only a single external trigger. The same modulator is also used to Q-switch, mode-lock and cavity dump the same laser. The use of the modulator results in a single laser being able to generate pulses in three duration ranges, i.e., approximately 20 ns, approximately 2 ns and approximately 70 ps. A similar modulator is used to suppress the pre-pulse generated by a regenerative amplifier and help attain a 105 contrast ratio between signal and pre-pulse. Other modulators and applications are presented, including an approximately 30 ps Pockels cell for use as an optical gate.
