“Spatio-temporal Femtosecond Laser pulse Shaping for Accelerator Physics”
High Energy (few MeV- few 10’s of MeV) femtosecond electron bunches are nowadays mandatory in several domains gathering Accelerator Physics and Laser-Matter interaction, as for instance Laser/Plasma Wakefield Acceleration, Free Electron Laser, Generation of Coherent Thz or Ultrashort X-rays light sources. A program, aiming at exploring the ways to produce such beams in a compact manner has been recently initiated in the Saclay/Orsay area, France. It involves several laboratories: CNRS/Laboratoire de l’Accelérateur Linéaire (LAL), CEA/Laboratoire d’Interaction-Dynamique-Laser (LIDyL), CNRS/Laboratoire de Physique des Gaz et des Plasmas (LPGP), and the Centre Laser de l’Université Paris Sud in Orsay (CLUPS).
This program is currently under implementation and first results are expected in winter 2016-2017. The primary goal in the first experiments of such a program is to obtain femtoseconds electron bunches from the PHIL 5-10 MeV RF-photoinjector platform, coupled with the 50 fs-long CPA-based Ti:Sa laser facility LASERIX, and to investigate their improved features in terms of brightness under different regimes, from classical photoemission to non-linear multiphoton emission.
As a mandatory task for achieving these goals, the laser team aims at conceiving, designing and operating an integrated instrumental system which will allow to spatiotemporally shape ultrashort (up to 100 fs) UV laser pulses (266 nm). Such a set-up will rely on the use of refractive and diffractive optical elements, together with a control of the optical dispersion, in order to handle the spatial and temporal features of a broadband laser pulse.
The Postdoctoral fellow, who will belong to the laser team (CNRS/LAL, LASERIX), will mostly take up this challenging program, in order to achieve the highest laser versatility in terms of available pulse energy (up to 1 mJ), single pulse length (few tens of femtoseconds and few picoseconds), and pulse shape, eventually for both IR and visible or UV pulses.
The postdoctoral fellow will have to study and implement new strategies, relying on the different approaches that can be used to shape the beam, for instance in the temporal domain, based on a linear system or a combination of linear systems.
In the experiments, multiple skills and/or a very synergic operation are required from intervenes, as they deal with the laser pulse handling and optimization, the photoinjector operation and development, and the electron beam transport and characterization. The postdoctoral fellow will totally behave in this dynamical environment, benefitting of a high exchange level.
EXPECTED PROFILE
Applicants are expected to hold a PhD degree in physics or in a related field.
The candidate should have a strong attraction for experiments.-
An expertise in ultrashort pulsed lasers would be a significant advantage, especially on CPA-based Ti:Sa lasers.
Good programming and computational skills would be an added value.
The eligible candidate should be able to communicate at a scientific level in English. Knowledge of French can also be useful.
The postdoc is two years for an immediate startup in 2016.
The interested candidates should apply quickly.The applications (including a detailed CV, a cover letter, a list of coordinate of supervisor) are to be sent to :
