Comment on Physics Nobel Prize 2018 by Dr. Amelle Zair in the Guardian


Amelle is a Lecturer in advanced photonics in the Physics Department at King’s College London. She is head of ULTRAFAST LASER SCIENCES and ATTOSECOND PHYSICS.

After a MSc in laser-matter interaction at Orsay-Ecole Polytechnique France, She was awarded her PhD  on “Production and characterisation of XUV attosecond pulses” in 2006 from University of Bordeaux ‘Centre for intense lasers and applications’; which she obtained with the highest distinction.

These attosecond pulses are known to be the shortest flash of coherent light ever achieved and the attosecond community is growing stronger worldwide in the last decades. Amelle is contributing to the UK effort on Attosecond Physics.

After her PhD she joined  world recognised groups in ultrafast physics (ETH Zurich and USAL ) for postdoctoral studies where she discovered of Quantum Path Interferences “QPI” in high order harmonic generation process at the heart of the attosecond control of matter under strong electromagnetic fields.    

Following her postdoctoral studies, she was awarded an EPSRC CAF fellowship in 2011 and she built her own group at Imperial College London where she led two novel investigation lines:  capturing  attosecond dynamics in atoms and molecules using attosecond quantum path interferometry,  and  new generation of high repetition rate Yb femtosecond laser for high repetition rate attosecond physics.

She recently joined our Department and she leads the ATTOPHYSIC@KINGS initiative. She has a keen interest in equality and diversity and is a member of the JUNO committee.

Research interests:

  • ultrafast laser-matter interaction
  • strong field physics
  • capturing and controlling attosecond time scaled phenomena
  • next generation of femtosecond and attosecond sources
