Observation of ultrafast laser-plasma evolution by pump-probe reflectometry and Doppler spectrometry
Amitava Adak, Prashant Kumar Singh, Amit D. Lad +2
We demonstrate pump-probe techniques, namely the Doppler spectrometry and the reflectometry in detail, which directly capture the time-resolved ultrafast evolution of high intensit…
Generation of a strong reverse shock wave in the interaction of a high-contrast high-intensity femtosecond laser pulse with a silicon target
Kamalesh Jana, Amit D. Lad, Moniruzzaman Shaikh +6
We present ultrafast pump-probe reflectivity and Doppler spectrometry of a silicon target at relativistic laser intensity. We observe an unexpected rise in reflectivity to a peak a…
Absorption of High Intensity, High Contrast Femtosecond Laser Pulses by a Solid
Amitava Adak, Amit D. Lad, Moniruzzaman Shaikh +3
The basic understanding of high-intensity femtosecond laser absorption in a solid is crucial for high-energy-density science. This multidimensional problem has many variables like…
Evidence of new finite beam plasma instability for magnetic field generation
Amita Das, Atul Kumar, Chandrasekhar Shukla +8
We demonstrate by computer simulations, laser plasma experiments, and analytic theory that a hitherto unknown instability is excited in the beam plasma system with finite transvers…
