ABSTRACT:
In order to provide an optical sampling waveform measuring apparatus which can measure an ultra-high speed optical signal accurately by using a stable, narrow pulse, and a low timing jitter sampling optical pulse, an optical sampling waveform measuring apparatus is provided with a passive mode-locked fiber ring laser for generating a sampling optical pulse and a cavity length varying device which adjusts the cavity length in a passive mode-locked fiber ring laser.
