Journal ArticleDOI
Direct observation of turbulent magnetic fields in hot, dense laser produced plasmas
Sudipta Mondal,V. Narayanan,W. J. Ding,Amit D. Lad,Biao Hao,Saima Ahmad,Wei-Min Wang,Zheng-Ming Sheng,Sudip Sengupta,Predhiman Kaw,Amita Das,G. Ravindra Kumar +11 more
TL;DR: The results are not only fundamentally interesting but should also arouse interest on the role of magnetic turbulence induced resistivity in the context of fast ignition of laser fusion, and the possibility of experimentally simulating such structures with respect to the sun and other stellar environments.
Journal ArticleDOI
A compact laser-driven plasma accelerator for megaelectronvolt-energy neutral atoms
TL;DR: In this paper, a megaelectronvolt beam of atoms is generated by ionizing argon clusters, and then neutralizing the ions using Rydberg atoms, which demonstrates a high neutral yield and could find an important application as a sensitive probe of matter.
Journal ArticleDOI
Highly enhanced hard x-ray emission from oriented metal nanorod arrays excited by intense femtosecond laser pulses
Sudipta Mondal,Indrani Chakraborty,Saima Ahmad,Daniel R. Carvalho,Prashant Kumar Singh,Amit D. Lad,V. Narayanan,Pushan Ayyub,G. Ravindra Kumar,Jian Zheng,Zheng-Ming Sheng +10 more
TL;DR: In this article, the authors reported a 43-fold enhancement in hard x-ray emission from copper nanorod arrays when excited by 30-fs, 800-nm laser pulses with an intensity of ${10}^{16}$ W/cm${}^{2}$.
Journal ArticleDOI
Emission spectroscopy of laser-ablated Si plasma related to nanoparticle formation
V. Narayanan,Raj K. Thareja +1 more
TL;DR: In this paper, the laser ablation of Si in vacuum, and in the presence of helium ambient at 1 and 10 Torr, respectively, is reported, where optical emission spectroscopy and images of the plume are used to study the spatial and temporal variation of the silicon plasma.
Journal ArticleDOI
Macroscopic transport of mega-ampere electron currents in aligned carbon-nanotube arrays.
Gourab Chatterjee,Prashant Kumar Singh,Saima Ahmed,Alexander Robinson,Amit D. Lad,Sudipta Mondal,V. Narayanan,Iti Srivastava,Nikhil Koratkar,John Pasley,John Pasley,A. K. Sood,G. Ravindra Kumar +12 more
TL;DR: It is demonstrated that aligned carbon-nanotube arrays are efficient transporters of laser-generated mega-ampere electron currents over distances as large as a millimeter.
