Physics Colloquium
Have you ever seen the shadow of a laser beam? And Quantum Telescopes

Dr. Raphael Abrahao

Brookhaven National Lab

Event Details:
I will talk about two recent optical advances. First, have you ever seen the shadow of a laser beam? Is this even possible? Under certain conditions, a laser beam can control the transmittance of another laser beam creating a visible shadow. This new effect, called the laser shadow effect, opens many applications in new ways to manipulate light. In the second part, I will discuss how quantum optics can benefit the development of a new kind of telescope systems. I will give an overview of the progress towards quantum telescopes and highlight some key breakthroughs in detectors and a recent milestone in working with multiple frequencies of light at the same time.

Bio:
Raphael A. Abrahao obtained his Electrical Engineering Degree and Master’s from the University of Campinas, Brazil, and his PhD from the School of Mathematics and Physics at the University of Queensland, Australia. Dr. Abrahao was a postdoctoral fellow at the University of Ottawa, Canada, researching quantum optics and photonics prior to joining the Brookhaven National Laboratory, NY, USA, as a postdoctoral research associate working on quantum telescopes and X-ray quantum technologies.
