Continuous wave terahertz frequency spectroscopy and imaging for explosives detection and security screenings
DownloadFall 2011
Continuous-wave terahertz (THz) spectroscopy was performed on high explosive materials using the Firefly-THz optical parametric oscillator (OPO). Cyclotetramethylene-tetranitramine (HMX), cyclotrimethylene-trinitramine (RDX), pentaerythritol-tetranitrate (PETN) and Composition-4 were scanned...

Exploiting second-order nonlinear phenomena for the generation and detection of coherent terahertz electric fields
DownloadSpring 2022
This thesis explores terahertz radiation sources and detectors, where the driving physical mechanism for generation and detection is second-order nonlinear phenomena. The heart of this work considers novel crystals and waveguiding arrangements for terahertz radiation generation and/or detection...

Spring 2024
We investigate the microscopic nature of charge-carrier conduction in nanoscale semiconducting materials using time-resolved terahertz spectroscopy (TRTS). TRTS uses picosecond pulses of terahertz radiation (0.5-2.5 THz) to explore photoexcited charge-carrier lifetimes and dynamics with...

Fall 2017
Ultrafast terahertz (THz) microscopy is an emerging field of research that leverages the imaging of picosecond electric field transients to explore free carrier responses from a near-field perspective. This thesis presents the first effort made to use an electro-optic imaging system to probe the...

Fall 2013
The main purpose of this thesis is to develop terahertz (THz) generation, detection, and spectroscopy techniques via ultrafast imaging methods. Sampling THz pulse waveforms with anoncollinear imaging technique was carried out. Full-field images of the THz electric field waveforms sampled in...
