Detection of picosecond laser pulses with nanosecond time resolution by use of analogue-to-digital converters

摘要

A photodetector-analogue-to-digital converter system with 1.8 ns rise and decay time is described. The photodetector waveform is fanned-out with power splitters and sampled with high-speed analogue-to-digital converters. The system is used to detect picosecond light pulses from a mode-locked Nd-glass laser with nanosecond time resolution.
