Paper Abstract

A compact optical sampler has been developed for the imaging of single-shot optical or electrical pulses. The analyzed duration is 400 ps, and the temporal sampling rate is 4 ps (250 GSa/s). The spectral density of the input signal is restored in the resulting data until 35 GHz. The device consists of a 50 Ohms propagation microstrip structure, lined by periodically arranged ultra-fast photoconductive switches. When illuminated, these switches short the propagation line to storing capacitors. To operate the device, the input signal is injected onto the line; when the signal to analyze is displayed along the line, facing the optical gates, these gates are switched on, and the storing capacitors collect an amount of charges related to the voltage present on the line. When an optical or X-ray pulse is on analysis, the electrical signal injected into the propagation line is delivered by a CdTe very fast detector. This device has been operated with a femtosecond laser. The analysis of a single pulse through the optical sampler results in an amplitude versus time curve, exhibiting temporal characteristics very close to those measured with a classical sampling head (repetitive signal) and much shorter than those measured with single shot existing analyzer.
