Research Summary:

My research area is in the experimental atomic, molecular and optical physics in particular photon-atom interactions through polarization and photo-ionization spectroscopy using a novel nanosecond pump-probe pulse laser technique. Bayram group foucs on the two following projects to investigate:

1. Collisional dynamics between the excited alkali atom and rare-gas atom using a two-photon polarization spectroscopy using pump-probe technique,
2. Rydberg state dynamics using photoionization spectroscopy in conjunction with electron imaging technique - fascinating and powerful technique that takes snapshots of the angular distributions of atoms.

Dr. Bayram is also interested in developing techniques for frequency narrowing and beam quality improvements of external cavity high-power broad-area lasers. Such work has spurred a great interest for military, industrial, scientific and medical applications, specifically for better medical imaging of the lungs and biological tissues.
