Circuit for synchronizing a mode-locked oscillator-amplifier dye laser with a streak camera detection system

摘要

A synchronization circuit couples a mode-locked oscillator-amplifier laser to a streak camera and Vidicon detection system. A sync signal from a mode-locker driver and a sync signal from a Nd:YAG pump laser act as basic circuit start signals. The circuit, with appropriate electronic timing delays, generates a Q-switch signal to the Nd:YAG laser to control the amplifier pump pulses to overlap with a dye laser pulse as it arrives in each stage of an optical amplifier chain.
