| 1 | The Apollon 10 PW laser: experimental and theoretical investigation of the temporal characteristics显示文摘The objective of the Apollon 10 PW project is the generation of 10 PW peak power pulses of 15 fs at 1 shot min^(-1). In this paper a brief update on the current status of the Apollon project is presented, followed by a more detailed presentation of our experimental and theoretical investigations of the temporal characteristics of the laser. More specifically the design considerations as well as the technological and physical limitations to achieve the intended pulse duration and contrast are discussed. | D.N.Papadopoulos J.P.Zou C.Le Blanc G.Chriaux P.Georges F.Druon G.Mennerat P.Ramirez L.Martin A.Frneaux A.Beluze N.Lebas P.Monot F.Mathieu P.Audebert | 2016 | High Power Laser Science and Engineering2016，4，3： | 6 |
| 2 | Design and current progress of the Apollon 10 PW project显示文摘The objective of the Apollon project is the generation of 10 PW peak power pulses of 15 fs at 1 shot/minute.

| 3 | Spectral broadening for multi-Joule pulse compression in the APOLLON Long Focal Area facility显示文摘Spectral-broadening of the APOLLON PW-class laser pulses using a thin-film compression technique within the longfocal-area interaction chamber of the APOLLON laser facility is reported,demonstrating the delivery of the full energy pulse to the target interaction area.The laser pulse at 7 J passing through large aperture,thin glass wafers is spectrally broadened to a bandwidth that is compatible with a 15-fs pulse,indicating also the possibility to achieve sub-10-fs pulses using 14 J.Placing the post-compressor near the interaction makes for an economical method to produce the shortest pulses by limiting the need for high damage,broadband optics close to the final target rather than throughout the entire laser transport system. | P.-G.Bleotu J.Wheeler D.Papadopoulos M.Chabanis J.Prudent M.Frotin L.Martin N.Lebas A.Freneaux A.Beluze F.Mathieu P.Audebert D.Ursescu J.Fuchs G.Mourou | 2022 | High Power Laser Science and Engineering2022，10，2： | 0 |
| 4 | Post-compression of high-energy,sub-picosecond laser pulses显示文摘The post-compression technique based on self-phase modulation of high-energy pulses leads to an increase in achievable peak power and intensity.Typically,the pulses considered in experiments have been less than 100 fs in duration.Here,the method is applied to the ELFIE laser system at the LULI facility,for a pulse of 7 J energy and an initial measured duration of 350 fs.A 5-mm-thick fused silica window and a 2 mm cyclic-olefin polymer were used as optical nonlinear materials.The 9 cm diameter beam was spectrally broadened to a bandwidth corresponding to 124 fs Fourier-limited pulse duration,and then it was partly post-compressed to 200 fs.After measuring the spatial spectra of the beam fluence,a uniform gain factor of 4 increase in the fluctuations over the studied range of frequencies is observed,due to small-scale self-focusing. | P.-G.Bleotu J.Wheeler S.Yu.Mironov V.Ginzburg M.Masruri A.Naziru R.Secareanu D.Ursescu F.Perez J.De Sousa D.Badarau E.Veuillot P.Audebert E.Khazanov G.Mourou | 2023 | High Power Laser Science and Engineering2023，11，2： | 0 |
| 5 | Characterization and performance of the Apollon short-focal-area facility following its commissioning at 1 PW level显示文摘We present the results of the first commissioning phase of the short-focal-length area of the Apollon laser facility(located in Saclay,France),which was performed with the first available laser beam(F2),scaled to a nominal power of 1 PW.Under the conditions that were tested,this beam delivered on-target pulses of 10 J average energy and 24 fs duration.Several diagnostics were fielded to assess the performance of the facility.The on-target focal spot and its spatial stability,the temporal intensity profile prior to the main pulse,and the resulting density gradient formed at the irradiated side of solid targets have been thoroughly characterized,with the goal of helping users design future experiments.Emissions of energetic electrons,ions,and electromagnetic radiation were recorded,showing good laser-to-target coupling efficiency and an overall performance comparable to that of similar international facilities.This will be followed in 2022 by a further commissioning stage at the multipetawatt level. | K.Burdonov A.Fazzini V.Lelasseux J.Albrecht P.Antici Y.Ayoul A.Beluze D.Cavanna T.Ceccotti M.Chabanis A.Chaleil S.N.Chen Z.Chen F.Consoli M.Cuciuc X.Davoine J.P.Delaneau E.d’Humieres J.-L.Dubois C.Evrard E.Filippov A.Freneaux P.Forestier-Colleoni L.Gremillet V.Horny L.Lancia L.Lecherbourg N.Lebas A.Leblanc W.Ma L.Martin F.Negoita J.-L.Paillard D.Papadopoulos F.Perez S.Pikuz G.Qi F.Quere L.Ranc P.-A.Soderstrom M.Sciscio S.Sun S.Vallieres P.Wang W.Yao F.Mathieu P.Audebert J.Fuchs | 2021 | Matter and Radiation at Extremes2021，6，6： | 0 |
