Abstract:: In an effort to develop an optical-acoustical understanding of ultrasound contrast agent microbubble dynamics in a micro-environment that resembles blood vessels, this thesis presents experimental work on optical trapping and acoustical probing of ultrasound contrast agent microbubbles confined in regenerated cellulose capillaries. First, we showed by acoustical means that the...

Creator:: Swanson, Thomas B.
Abstract:: A low velocity, low temperature beam of atoms is produced from a two-dimensional magneto-optic trap known as an atomic funnel. The funnel provides simultaneous spatial and velocity compression of atoms and will provide a source for a three-grating atomic interferometer. Rubidium atoms from an oven are slowed by chirped cooling...

Creator:: Cibula, Matthew A.
Abstract:: The development and some applications of holographic optical tweezers (HOT) are presented. Our HOT system uses a spatial light modulator (SLM) to control the location and properties of the optical trap. We have developed a method for optimizing the diffraction efficiency of a SLM that can be applied in situ...

Creator:: Wells, Blake
Abstract:: A method for determining bandgap energy using diffuse reflection is presented. The method uses bifurcated fiber optic cables to measure the diffuse reflection of diffusely reflective materials. The absorption spectrum is extrapolated from the diffuse reflection spectrum and used to determine the bandgap of powdered materials. The theory of nonspecular...

Creator:: Russell, Joshua A.
Abstract:: A method for bandgap energy determination using di use re ection is presented and compared to the traditional integrating sphere method. We have found the bandgap energies of ZnO, TiO₂, Cu₂O, Si, SnZrS₃, SnZrSe₃, Sn₂S₃, and BiCuOSe powders with both methods and found they agree within 0.03 eV. We have...

Creator:: Silva, Nancy J.
Abstract:: We have developed simple and inexpensive laser systems using grating-feedback diode lasers with electronic feedback to the injection current. These grating-feedback lasers can be continuously scanned up to 10 GHz and have a linewidth of 150 kHz. The three electronic frequency-stabilization systems we developed use polarization spectroscopy, etalon transmission and...

Creator:: Mayer, Shannon K.
Abstract:: A continuous, low-velocity, nearly monochromatic atomic beam is created using laser cooling and two-dimensional magneto-optic trapping. Rubidium atoms from an effusive oven are slowed and cooled using Zeeman-tuned slowing. The scattering force from a counter-propagating, frequency-stabilized diode laser beam is used to decelerate the thermal beam of atoms to a...
