| 1 | High-energy hybrid femtosecond laser system demonstrating 2×10 PW capability显示文摘We report on a two-arm hybrid high-power laser system(HPLS)able to deliver 2×10 PW femtosecond pulses,developed at the Bucharest-Magurele Extreme Light Infrastructure Nuclear Physics(ELI-NP)Facility.A hybrid frontend(FE)based on a Ti:sapphire chirped pulse amplifier and a picosecond optical parametric chirped pulse amplifier based on beta barium borate(BBO)crystals,with a cross-polarized wave(XPW)filter in between,has been developed.It delivers 10 mJ laser pulses,at 10 Hz repetition rate,with more than 70 nm spectral bandwidth and high-intensity contrast,in the range of 1013:1.The high-energy Ti:sapphire amplifier stages of both arms were seeded from this common FE.The final high-energy amplifier,equipped with a 200 mm diameter Ti:sapphire crystal,has been pumped by six 100 J nanosecond frequency doubled Nd:glass lasers,at 1 pulse/min repetition rate.More than 300 J output pulse energy has been obtained by pumping with only 80%of the whole 600 J available pump energy.The compressor has a transmission efficiency of 74%and an output pulse duration of 22.7 fs was measured,thus demonstrating that the dual-arm HPLS has the capacity to generate 10 PW peak power femtosecond pulses.The reported results represent the cornerstone of the ELI-NP 2×10 PW femtosecond laser facility,devoted to fundamental and applied nuclear physics research. | François Lureau Guillaume Matras Olivier Chalus Christophe Derycke Thomas Morbieu Christophe Radier Olivier Casagrande Sébastien Laux Sandrine Ricaud Gilles Rey Alain Pellegrina Caroline Richard Laurent Boudjemaa Christophe Simon-Boisson Andrei Baleanu Romeo Banici Andrei Gradinariu Constantin Caldararu Bertrand De Boisdeffre Petru Ghenuche Andrei Naziru Georgios Kolliopoulos Liviu Neagu Razvan Dabu Ioan Dancus Daniel Ursescu | 2020 | High Power Laser Science and Engineering2020，8，4： | 4 |

| 16 | Joint receiving mechanism based on blind equalization with variable step size for M-QAM modulation显示文摘The problem of inter symbol interference( ISI) in wireless communication systems caused by multipath propagation when using high order modulation like M-Q AMis solved. Since the wireless receiver doesn't require a training sequence,a blind equalization channel is implemented in the receiver to increase the throughput of the system. To improve the performances of both the blind equalizer and the system,a joint receiving mechanismincluding variable step size( VSS) modified constant modulus algorithms( MC-MA) and modified decision directed modulus algorithms( MD DMA) is proposed to ameliorate the convergence speed and mean square error( MSE) performance and combat the phase error when using high order QAM modulation. The VSS scheme is based on the selection of step size according to the distance between the output of the equalizer and the desired output in the constellation plane. Analysis and simulations showthat the performance of the proposed VSS-MCMA-MD DMA mechanismis better than that of algorithms with a fixed step size. In addition,the MCMA-MDDMA with VSS can performthe phase recovery by itself. | 卢继华 Abdallah Elhirtsia AHMED 王晓华 Kheddar BOUDJEMAA | 2015 | Journal of Beijing Institute of Technology2015，24，3： | 0 |
