SHORT PULSE LIGHT GENERATING DEVICE AND MUTUAL CORRELATION MEASUREMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a short pulse light generating device of which the output time of a short pulse light is continuously varied while the optical path of the short pulse light is kept constant and to provide a mutual correlation measurement device in which the short pulse light generating device is used. SOLUTION: The short pulse light generating device 2 is composed of a fiber laser 11, an acoustic and optical modulator 12, a polarized wave maintaining type optical fiber F1, an optical filter 15 or the like. The soliton pulse of each short pulse light outputted from the short pulse light generating device 2 is used as a reference short pulse, superimposed with a short pulse light to be measured on PBS32 and is made incident on an avalanche diode 33. Further, a signal outputted from the avalanche diode 33 is observed on an oscilloscope 34.
