Abstract

A 5 ps resolution streak camera associated with an analogic video storage system has been developed: the display of the trace on the TV monitor allows the experimenter to evaluate immediately after each laser shot the temporal characteristics of a single mode-locked pulse delivered by a Nd:YAG laser or by a Nd: glass bandwidth limited tunable laser. The memorization of the video signal by means of a storage tube permits an accurate analysis of the light pulse width ; the display includes temporal and intensity calibration signals. In order to reduce the temporal fluctuations of the triggering system of the streak camera, it has been developed (1) an avalanche transistor sweep generator, the sweep voltage presents a linearity better than 10 To over 4 cm of the phosphor screen and a rate of 180 ps/cm ; (ii) a high sensitive tunnel diode trigger, the measurements show that a variation of the laser envelope amplitude of a factor 5 leads to a time jitter of less than 30 ps. Furthermore, using the aforementioned circuit in conjunction with a Pockets cell (CID'A crystal), it is shown that for the previous envelope fluctuations the single output pulse has an amplitude variation of less than 20 %.
