Abstract

In recent years important progress has been made in electrical signal analysis. With the advent of subpicosecond cw mode-locked dye lasers, new optoelectronic techniques have been developed capable of time-resolving electrical signals with picosecond precision and submiillvoit sensitivity. Using laser-induced photoconductivity in semiconductors possessing ultrashort carrier lifetimes, Auston¹ achieved a gating time of <3 psec. Recently,^2,3 we developed a sampling system that utilizes iOO-fsec laser pulses and the ultrafast response of the eiectrooptic effect in a traveling wave Pockels cell (Fig. 1).
