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...

Masters Thesis
A contribution to the development of wide band-gap nonlinear optical and laser materials

Creator:

Stone-Sundberg, Jennifer L.

Abstract:

The primary focus of this work is on examining structure-property relationships of interest for high-power nonlinear optical and laser crystals. An intuitive and simply illustrated method for assessing the nonlinear optical potential of structurally characterized noncentrosymmetric materials is introduced. This method is applied to materials including common quartz and tourmaline...

Dissertation
A new trigonal huntite material and subgroup relationships between crystallographic space groups

Creator:

Hruschka, Michael Archimedes and Hruschka, Michael A.

Abstract:

The use of an adjacency matrix to determine distant (not maximal or minimal) subgroup and supergroup relationships between crystallographic spacegroup types is described. Full lists of space-group types that are supergroups and subgroups for every space-group type were compiled. A list of the space-group types connected to each space-group type...
