Best optics papers in 2012 by Optics & Photonics News

The research group of Prof. Paolo De Natale is in the video of the top three photonics research in 2012.

In this special issue, Optics & Photonics News highlights the best peer-reviewed optics research papers published over the past 12 months. A panel of editors reviewed close to 80 submitted summaries from scientists all over the globe, selecting for publication the 30 stories that they felt most clearly communicated breakthroughs of interest to the optics community.

A 5-minutes video tells about the top three research, among which there is the work by Prof. Paolo De Natale's group on radiocarbon dating with pure optical methods (video starts at 3 minutes and 9 seconds).

Here is the abstract: radiocarbon (14C), the natural clock for dating organic matter, is a very elusive atom. Its concentration is about one part per trillion. For the past 30 years, accelerator mass spectrometry (AMS) has been adopted as the standard method for dating organic samples via radiocarbon. AMS requires a smaller carbon mass and shorter measurement times than the old standard method of liquid scintillation counting. However, AMS requires huge, expensive and high-maintenance experimental facilities.
