Start-to-end modelling of laser-plasma acceleration, beam transport and dose deposition of very high-energy electrons for radiotherapy
Rajakrishna Kalvala, Anton Golovanov, Arnaud Courvoisier +4
Radiotherapy using very high-energy electron (VHEE) beams generated by a laser-plasma accelerator has garnered significant interest due to its dose distribution capabilities and po…
On the absence of the electrostriction force in dilute clouds of cold atoms
Arnaud Courvoisier, Nir Davidson
The momentum of light in a medium and the mechanisms of momentum transfer between light and dielectrics have long been the topic of controversies and confusion. We discuss here the…
Direct reconstruction of the band structure of a 1D optical lattice with thermal atoms
Arnaud Courvoisier, Amruta Gadge, Nir Davidson
We report on a simple method to reconstruct the band structure of a 1D optical lattice using a thermal cloud with a momentum spread of about two-photon recoils. We image the moment…
Deviations from generalized Equipartition in Confined, Laser Cooled Atoms
Gadi Afek, Alexander Cheplev, Arnaud Courvoisier +1
We observe a significant steady-state deviation from the generalized equipartition theorem, one of the pivotal results of classical statistical mechanics, in a system of confined,…
High phase space density loading of a falling magnetic trap
Ido Almog, Jonathan Coslovsky, Gil Loewenthal +2
Loading an ultra-cold ensemble into a static magnetic trap involves unavoidable loss of phase space density when the gravitational energy dominates the kinetic energy of the ensemb…
High resolution structural characterisation of laser-induced defect clusters inside diamond
Patrick S. Salter, Martin J. Booth, Arnaud Courvoisier +2
Laser writing with ultrashort pulses provides a potential route for the manufacture of three-dimensional wires, waveguides and defects within diamond. We present a transmission ele…
Femtosecond laser inscription of Bragg grating waveguides in bulk diamond
V. Bharadwaj, A. Courvoisier, T. T. Fernandez +7
Femtosecond laser writing is applied to form Bragg grating waveguides in the diamond bulk. Type II waveguides are integrated with a single pulse point-by-point periodic laser modif…
Observing Power-Law Dynamics of Position-Velocity Correlation in Anomalous Diffusion
Gadi Afek, Jonathan Coslovsky, Arnaud Courvoisier +2
In this letter we present a measurement of the phase-space density distribution (PSDD) of ultra-cold \Rb atoms performing 1D anomalous diffusion. The PSDD is imaged using a direct…
Inscription of 3D waveguides in diamond using an ultrafast laser
Arnaud Courvoisier, Martin J. Booth, Patrick S. Salter
Three dimensional waveguides within the bulk of diamond are manufactured using ultrafast laser fabrication. High intensities within the focal volume of the laser cause breakdown of…
