Five major publications in the last five years

 Laboratory formation of a scaled protostellar jet by co-aligned poloidal magnetic field
B. Albertazzi [...] and J. Fuchs
Science 346, 325 (2014)
this paper not only demonstrates a mechanism proposed theoretically to explain the long-range stability of astrophysical jets, but it also shows that collimated and dense plasma jets can be produced in the laboratory, opening up many more research opportunities
 
 Charge equilibrium of a laser generated carbon ion beam in warm dense matter
M. Gauthier [...] and J. Fuchs
Phys. Rev. Lett. 110, 135003 (2013)
this paper presents the first measurement of charge equilibrium of a projectile transiting through in a hot, dense plasma; the method used here is the first step toward investigating ion-dense plasma interactions
 
 High-power laser delocalization in plasmas leading to long-range beam merging
M. Nakatsutsumi [...] and J. Fuchs
Nature Phys. 6, 1010 (2010)
first observation of laser beams non-linear coupling in a plasma
 
 Experimental evidence of short light pulse amplification using strong-coupling stimulated Brillouin scattering in the pump depletion regime
L. Lancia [...] and J. Fuchs
Phys. Rev. Lett. 104, 025001 (2010)
first proof that ions waves in plasmas can be used to amplify lasers
 
 Picosecond short-range disordering in isochorically heated aluminum at solid density
A. Mančić [...] and J. Fuchs
Phys. Rev. Lett. 104, 035002 (2010)
first measurement of ps-scale phase transition in isochorically heated matter

TECHNOLOGY TRANSFER

In the early 2000, I worked implementing (for the first time in France) adaptive optics on a high-power laser. This was made in the frame of a PhD thesis, following which the student created a startup (PHASICS) that has developed into a successful company (http://www.phasicscorp.com/). More recently, I helped the creation (in Jan. 2014) of another company "Light Stream Labs" (http://www.lightstreamlabs.com/), which aims to promote the expertise of the LULI laboratory in the realization of laser-matter diagnostic and targets systems.
