| Outline of Final Research Achievements |
We develop the spectroscopic system to detect vibrational optical activity with high sensitivity and high spectral resolution by using chirped pulse upconversion, where mid-infrared probe pulses are mixed with chirped pulses and converted into the visible region. It is shown that LiGaS2 is the best candidate for our purpose. The performance of the spectroscopic system is as follows: Spectral resolution of 2.8 cm, time resolutions of 0.2 ps, and noise level of 10-4. We also demonstrated that the mid-infrared spectroscopy using narrowband pump pulses with tunable frequency and polarization is sensitive to molecular structures.
