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.
