Laszlo Ujj, Ph.D., Associate Professor of Physics
Department of Physics, School of Science and Engineering (SSE), University of West Florida
Address and Office Location:
Please note: Update (May 2012). Please note: I am back to UWF and getting active again here. The best way to communicate with me is E-mail..
Laser Spectroscopy Laboratory of SSE, Department of Physics
Teaching: I thought all of the following courses several times, so get ready to learn them from me when the time comes.
Public demonstrations and lectures for entertainment, educational, and recruitment purposes in Laser Spectroscopy, Physics and Optics (contact SSE)
1. Theoretical models of “phase retrieval” methods (I love this part of math and physics)
2. Development of spectral analyses software in LabView for coherent Raman spectroscopy (this is my own way to contribute to spectroscopy)
Physics Students of UWF: I am currently accepting applications to work on these projects with me.
Research Interest (in general):
1. Applications of vibrational spectroscopies in biology and in medical sciences.
2. Novel vibrational spectroscopies with ultrafast lasers (theoretical and experimental realizations).
3. Manipulations, e.g. driven rotations of molecules with laser pulses.
4. Realization of quantum information processing in molecular systems (if it is possible).
Engaging students in scientific research is an integral part of my research activity. Most of the recent publications have undergraduate student participation.
