An amplified femtosecond laser system for material micro-/nanostructuring with an integrated Raman microscope

Zalloum, Othman H. Y.; Parrish, Matthew; Terekhov, Alexander; Hofmeister, William (The University of Tennessee Space Institute,, 2010-05-27)

In order to obtain new insights into laser-induced chemical material modifications, we introduce a novel combined approach of femtosecond pulsed laser-direct writing and in situ Raman microscopy within a single experimental ...
Directional eye fixation sensor using birefringence-based foveal detection

Gramatikov, Boris I.; Zalloum, Othman H. Y.; Wu, Yi Kai; Hunter, David G.; Guyton, David L. (2007-04)

We recently developed and reported an eye fixation monitor that detects the fovea by its radial orientation of birefringent nerve fibers. The instrument used a four-quadrant photodetector and a normalized difference ...

Light Emission From Hydrogenated and Unhydrogenated Si-Nanocrystal/Si Dioxide Composites Based on PECVD-Grown Si-Rich Si Oxide Films

Comedi, David; Zalloum, Othman H. Y.; Wojcik, Jacek; Mascher, Peter (IEEE JOURNAL OF SELECTED TOPICS IN QUANTUM ELECTRONICS,, 2006-12)

Hydrogenated and unhydrogenated Si-nanocrystal/Si dioxide (Si-nc/SiO2) composites were obtained from SiyO1−y (y = 0.36, 0.42) thin films deposited by plasma-enhanced chem- ical vapor deposition. The unhydrogenated ...
On femtosecond micromachining of HPHT single-crystal diamond with direct laser writing using tight focusing

Zalloum, Othman H. Y.; Parrish, Matthew; Terekhov, Alexander; Hofmeister, William (The University of Tennessee Space Institute,, 2010-06-03)

We investigate the formation of diversiform micro-/nanostructures in High-Pressure High-Temperature (HPHT) synthetic singlecrystal diamond by tight-focusing 200 fs regeneratively amplified Ti: Sapphire laser pulses centered ...
