Masaki Kando,Yuji Fukuda,Alexander S. Pirozhkov,Alexander S. Pirozhkov,Jinglong Ma,Izuru Daito,Liming Chen,T. Zh. Esirkepov,T. Zh. Esirkepov,Koichi Ogura,T. Homma,Yukio Hayashi,Hideyuki Kotaki,Akito Sagisaka,Michiaki Mori,James Koga,Hiroyuki Daido,Sergei V. Bulanov,Sergei V. Bulanov,Sergei V. Bulanov,Toyoaki Kimura,Yoshiaki Kato,Toshiki Tajima +22 more
TL;DR: The counterpropagating laser pulse reflection from the plasma wake wave accompanied by its frequency multiplication was detected in the experiment and produced a time-compressed frequency-multiplied pulse due to the double Doppler effect.
Journal ArticleDOI
Controlled electron injection into the wake wave using plasma density inhomogeneity
A. V. Brantov,T. Zh. Esirkepov,Masaki Kando,Hideyuki Kotaki,V. Yu. Bychenkov,Sergei V. Bulanov +5 more
TL;DR: In this article, the electron injection for the laser wake field accelerator, controlled through the plasma density inhomogeneity, is studied on a basis of analytical estimates and two-and three-dimensional particle-in-cell simulations.
Journal ArticleDOI

TL;DR: The demonstrated flying mirror reflectivity is close to the theoretical estimate for the parameters of the experiment, and the counterpropagating laser pulse is reflected and upshifted in frequency with a multiplication factor of 37-66, corresponding to the extreme ultraviolet wavelength.
Journal ArticleDOI
Observation of strong correlation between quasimonoenergetic electron beam generation by laser wakefield and laser guiding inside a preplasma cavity
Tomonao Hosokai,Kenichi Kinoshita,T. Ohkubo,Akira Maekawa,Mitsuru Uesaka,Alexei Zhidkov,Atsushi Yamazaki,Hideyuki Kotaki,Masaki Kando,K. Nakajima,Sergei V. Bulanov,Paolo Tomassini,Antonio Giulietti,Danilo Giulietti +13 more
TL;DR: A strong correlation between the generation of monoenergetic electrons and optical guiding of the pulse in a thin channel produced by picosecond laser prepulses is observed and is well corroborated by two-dimensional particle-in-cell simulations.
Journal ArticleDOI
On the design of experiments for the study of extreme field limits in the interaction of laser with ultrarelativistic electron beam

TL;DR: In this article, experiments on the collision of laser light and high intensity electromagnetic pulses generated by relativistic flying mirrors, with electron bunches produced by a conventional accelerator and with laser wake field accelerated electrons for studying extreme field limits in the nonlinear interaction of electromagnetic waves.
