Spring 2015
A new class of direct diode pumped ceramic disk lasers are emerging as attractive candidates for efficient high power amplifiers in industrial and scientific applications. This thesis discusses the development and characterization of a high gain laser module based on Yb:YAG ceramic laser media...

Design and Development of High-Power Pulse Transmitters for Underground Environmental Perception
DownloadFall 2022
The objective of this thesis is associated with designing a high-power Gaussian pulse transmitter for high-depth imaging applications. Two types of pulse transmitters are presented in this work. The former configuration is based on Step Recovery Diodes (SRDs), while the latter is based on...

Spring 2023
The study of energetic particles of solar and cosmic origin, and those accelerated in the planetary magnetopause, is integral to our developing understanding of the physical processes affecting space radiation in near-Earth space, interplanetary space, and Earth's upper atmosphere. In particular,...

Spring 2015
A longitudinally diode-pumped, passively Q-switched Yb:CaF2 laser has been developed and characterised using a Cr:YAG saturable absorber. A peak average output power of 914 mW at a repetition rate of 1314 Hz was obtained with a slope efficiency of 20%. The output pulse energy was 0.62 mJ with a...

Telikicherla Kandala, Anant Kumar
In-situ measurements of energetic particle precipitation in the near-Earth space environment are essential for understanding the governing physical processes responsible for this precipitation, as well as to elucidate the possible impacts of space radiation on the Earth’s atmosphere. This thesis...

Fall 2012
The Earth's magnetosphere is composed of energetic electrons and protons. It is important to verify average populations and energy distributions of these particles and quantify the effects of geomagnetic events on their populations and energy distributions. Abrupt changes have been observed in...

Fall 2012
Raman spectroscopy has the capability of providing detailed information about molecular structure, but the extremely small cross section of Raman scattering prevents this technique from applications requiring high sensitivity. Surface enhanced Raman scattering (SERS) on the other hand provides...

Laser Ablation Laser Induced Fluorescence for the Sensitive Detection of Heavy Metals in Water
DownloadFall 2010
Laser Induced Breakdown Spectroscopy LIBS is a fast non-contact technique for the analysis of the elemental composition using spectral information of the emission from a laser-induced plasma. For the LIBS studies in this thesis the focus has been in using very low energy, microjoule pulses in...

Fall 2010
In this thesis electron generation is studied via laser plasma interaction known as laser wakefield acceleration in two regimes of weakly relativistic and highly relativistic laser intensity regimes. The plasma targets consisted of gas jets photonionized by rising edge of the laser pulse to...

Spring 2018
Ultra-intense lasers (I > 10^18 W/cm^2) irradiating solid targets can produce bright, energetic (MeV) beams of protons, with potential applications from fusion energy to tumour treatment. Spatially and spectrally controlling these particle beams remains a challenge, however, and experimental and...
