New class of laser wavemeter breaks the glass ceiling

The precise wavelength of a laser is important in numerous applications, but measuring changes of wavelength to one part in ten thousand million has been quite demanding. Our group has invented a new technique for doing such measurements based on the random scattering of laser light from a rough surface. This breakthrough could revolutionise the use of lasers in certain applications in quantum technologies and in healthcare.

Celebrating 40 years of Optics Letters – Top Papers

OSA journal, Optics Letters, turns 40 this year and as part of the celebrations they are compiling a list of their top 100 cited articles. Currently numbers 26-100 are listed here. Numbers 1-25 will be released later in the year.

We are very pleased to note that our group leader, Prof. Kishan Dholakia, is featured on the list. The article, “Mechanical equivalence of spin and orbital angular momentum of light: an optical spanner” is number 53, with 539 citations as of Jan 4th 2017 (Clarivate Analytics).

Alternative impact: Tracking our publications with Altmetric

While citations are still the most recognised academic kudos, the growing use of digital media offers many different avenues for impact and dissemination of results. Altmetric tracks these alternative metrics to measure impact of publications. We are now adding Altmetric badges to our publication listings, hover over the badges for more information.

Why not check out our top 10 articles, currently ranking highest on Altmetric below.
