Investigating Low-Frequency Vibrations in Condensed Matter Using Time-Resolved Third-Harmonic Generation Spectroscopy

Creator:

Wang, Liang

Abstract:

In this thesis, I present a new method we developed to study low frequency (< 700 cm⁻¹) vibrational dynamics: Time-resolved third-harmonic generation (TRTHG) spectroscopy. Among a variety of vibrational spectroscopy techniques, TRTHG differentiates itself with robustness, versatility, and simplicity. In TRTHG experiment, that involves only two ultrashort laser pulses, the...

Second harmonic generation in polyacetylene

Creator:

Kircher, Jens

Abstract:

This study investigates nonlinear optical properties of matter. Nonlinear optical effects have found a wide field of applications such as the extension of the operation range of lasers to higher frequencies, material probes and optical image processing. A brief introduction to the most common nonlinear optical phenomena is given and...
