Colloquium: “Searching the Secrets of Nature using Photonics Physics” – Robert R. Alfano

PS 161

Friday, November 18, 2011 / 4:30pm

Robert R. Alfano



The talk will describe the salient properties of light and discuss breaking some of the commonly accepted rules and processes in nature. The following will be discussed: coherence of excitons in primary photon capture and energy transport processes in plant photosynthesis; stitching tissues together using hot vibrations excited by ultrafast laser pulses; breaking De Beers absorption law for deeper penetration of light in water due to ultrafast laser pulse being faster than the depopulation response times; twisting non planar light beam selection rules revealing new transitions in materials; and optical memory in scattering medium.


Robert R. Alfano, Distinguished Professor of Science and Engineering at The City College of the City University of New York, is a pioneer in the application of light and photonics technology to the study of biological, biomedical and condensed matter systems and a leader in inventing and using novel light sources as well as developing ultrafast laser spectroscopic techniques. His contributions to the field of photonics over the past 30 years of his professional career are documented in over 700 research articles, 108 patents, several edited volumes and conference proceedings, and well as over 10,000 citations. His research achievements include pioneering contributions in discovering new tunable Cr3+/Cr4+ lasers, developing laser spectroscopic and optical biomedical imaging techniques for noninvasive, pain-free detection and diagnosis of diseases. He has received his Ph.D. in physics from New York University. Received OSA Charles Hard Townes Award in 2008 for supercontinuum discovery and tunable laser development.
