Micron-Scale Mapping of Megagauss Magnetic Fields in Petawatt Laser-Solid Interactions
Gourab Chatterjee, Prashant Kumar Singh, A. P. L. Robinson +14
We report spatially and temporally resolved measurements of magnetic fields generated by petawatt laser-solid interactions with high spatial resolution, using optical polarimetry.…
Nanostructures and enhanced absorption in intense laser interaction with matter: effect of laser prepulses
P. P. Rajeev, S. Kahaly, S. Bose +4
Hard x-ray emission (20 - 200 keV) from plasmas produced by intense laser pulses on nanoparticle coated targets is compared with that from optically polished targets. The yield enh…
Comment on 'Intense picosecond x-ray pulses from laser plasmas by use of nanostructured velvet targets'
P. P. Rajeev, G. R. Kumar
Comment on the PRL paper.
Polarization independent hot electron production from modulated solid surfaces
P. P. Rajeev, G. Ravindra Kumar
We present measurements of hard x-rays in the 50-300 keV range from copper plasmas produced by 100 fs, 806 nm laser pulses at a peak intensity ~ 1016 W cm-2. Surface roughness, eve…
Laser-Generated Ultrashort Multi-Megagauss Magnetic Pulses in Plasmas
A. S. Sandhu, A. K. Dharmadhikari, P. P. Rajeev +4
We demonstrate ultrashort (6 ps), multi-Megagauss (27 MG) magnetic pulses generated upon interaction of an intense laser pulse (10^{16} Wcm^-2, 100 fs) with a solid target. The tem…
Metal nanoplasmas as bright sources of hard x-ray pulses
P. P. Rajeev, P. Taneja, P. Ayyub +2
We demonstrate a 13-fold increase in hard x-ray bremsstrahlung (10 - 200 keV) emitted by a copper plasma created by 100 fs, 806 nm pulses at Wcm. This enha…
