| Outline of Final Research Achievements |
An ultrafast optical imaging method utilizing time-resolved optical sampling has been developed. The apparatus was constructed using a twin mode-locked laser oscillator of variable cavity lengths, which share an excitation laser and an optical breadboard, for relative stability against environmental fluctuations. Their relative phase of the pulse repetition frequencies at higher harmonics was detected and locked after heterodyne down-conversion using a common microwave oscillator. An intensity cross-correlation width of ~70 fs, which was similar to those of auto-correlations, was obtained for a long time by an optical intensity correlator when locked. Optical imaging of complex molecular systems using the apparatus is under investigation.
