Oscillator phase noise measurements by picosecond synchroscanstreak camera

摘要

A new method-with picosecond resolution-allowing the recording ofnthe instantaneous time phase fluctuations of a crystal controllednoscillator is presented. The oscillator under test drives thenacoustooptic modelocker of a CW Nd:YAG laser associated with ansynchronously pumped dye laser. By means of a streak camera illuminatednby the ps dye laser pulses and synchronized by the oscillator signal thenstatistics of its zero crossings is analyzed
