Abstract

Vibrational spectroscopy is widely used in various fields where non-invasive molecular diagnosis is required, but conventional infrared and Raman spectroscopy techniques suffer from low measurement speed and therefore are used mainly for measuring static samples. Recent advancement of nonlinear frequency generation and conversion techniques allow us to develop sophisticated high-speed measurement techniques that make possible to measure dynamic phenomena with high temporal resolutions. In this talk, I introduce newly developed infrared absorption and Raman scattering spectroscopy techniques enabled by light sources with nonlinear optical techniques, including phase-controlled Fourier-transform infrared spectroscopy, rapid-scan Fourier-transform coherent Raman scattering spectroscopy, complementary vibrational spectroscopy and time-stretch infrared spectroscopy.
