| Outline of Final Research Achievements |
In this research, we have established a technique that can measure the oscillation of the electric field even when using a pulse longer than the period of the optical field, and we have advanced the research of the nonlinear optics which is sensitive to the oscillation of the optical field using that technique. We have investigated the process of the wavelength conversion from infrared light to visible light,
a kind of nonlinear optical process, by using the originally developed optical field waveform measurement method. It was observed that the efficiency of the wavelength conversion greatly changed depending on the phase of the input electric field. Moreover, it is shown that the phenomenon can be explained by the interference between the harmonics of various orders.
