| Outline of Final Research Achievements |
We have developed a spectral interferometer with high accuracy and high stability in order to evaluate the time-dependent polarization state of the third harmonics generated from aligned molecular samples. By using the developed system, we measured the polarization states of the third harmonics generated from aligned CO2 molecules, and found that the polarization state critically depends on the pressure of the sample molecules. The intensity and the ellipticity do not increase monotonically as the pressure increases but show 3-4 phases. A detailed propagation simulation of the pressure dependence will reveal the basic properties of molecules such as components of polarizability and hyperpolarizability.
