Report

Classical versus quantum views of intense laser pulse propagation in gases

Autor: Berman, S. A., Chandre, C., Dubois, J., Perin, M., Uzer, T.

Publikováno v: J. Phys. B: At. Mol. Opt. Phys. 52, 125601 (2019)

We study the behavior of reduced models for the propagation of intense laser pulses in atomic gases. The models we consider incorporate ionization, blueshifting, and other nonlinear propagation effects in an ab initio manner, by explicitly taking int

Coherent buildup of high harmonic radiation: the classical perspective

Autor: Berman, S. A., Dubois, J., Chandre, C., Perin, M., Uzer, T.

Publikováno v: Phys. Rev. A 97, 061402 (2018)

We present a classical model for high harmonic generation during the propagation of an intense laser pulse through an atomic gas. Numerical simulations of the model show excellent quantitative agreement with the corresponding quantum model for the bl

Hamiltonian fluid closures of the Vlasov-Amp{\`e}re equations: from water-bags to N moment models

Autor: Perin, M., Chandre, Cristel, Morrison, P. J., Tassi, E.

Moment closures of the Vlasov-Amp{\`e}re system, whereby higher moments are represented as functions of lower moments with the constraint that the resulting fluid system remains Hamiltonian, are investigated by using water-bag theory. The link betwee

Hamiltonian closures for fluid models with four moments by dimensional analysis

Autor: Perin, M, Chandre, C, Morrison, P. J., Tassi, E

Fluid reductions of the Vlasov-Amp{\`e}re equations that preserve the Hamiltonian structure of the parent kinetic model are investigated. Hamiltonian closures using the first four moments of the Vlasov distribution are obtained, and all closures prov

Final A&T Stages of the Gemini Planet Finder

Autor: Hartung, M., Macintosh, B., Poyneer, L., Savransky, D., Gavel, D., Palmer, D., Thomas, S., Dillon, D., Chilcote, J., Ingraham, P., Sadakuni, N., Wallace, K., Perin, M. D., Marois, C., Maire, J., Rantakyro, F., Hibon, P., Saddlemyer, L., Goodsell, S.

The Gemini Planet Imager (GPI) is currently in its final Acceptance & Testing stages. GPI is an XAO system based on a tweeter & woofer architecture (43 & 9 actuators respectively across the pupil), with the tweeter being a Boston Michromachines $64^2
