ABSTRACT:
A record is obtained of repetitive optical phenomena having durations in the picosecond or subpicosecond range by synchronizing the deflection of the electron image in an electron-optical streaking image tube with the repetition rate of a pulse train from a continuous wave mode-locked laser which supplies such pulses to the tube. Synchronization may be effected by supplying a reference frequency signal both to the laser and to the deflection electrodes in the image tube. The signal applied to the deflection electrodes may comprise a synchronized sinusoidal voltage signal and a slowly varying bias voltage signal. An optical multi-channel analyser may be used at the output of the image tube, linked to an oscilloscope or pen recorder.
