Paper Abstract

A numerical assessment of the role of phase noise in the synchroscan deflection signal and its effect on achievable streak camera temporal resolution is detailed and tested experimentally. The circuitry employed in the synchroscan streak operation of the Photochron IV camera system is described. The experimental performance of two synchronisation systems, (i) a passive configuration whereby the deflection signal is derived directly from a mode-locked pulse source and, (ii) an active system incorporating a tunnel-diode oscillator phase-locked to the laser, have been experimentally compared. By taking phase noise into account the circuitry has been appropriately optimised and this has permitted the demonstration, in synchroscan mode, of a limiting temporal resolution of 930 fs for the Photochron IV synchroscan-camera. Techniques to further enhance this performance and extend synchroscan operation further into the sub-picosecond domain will be outlined.
