Temporal Feedback Control of High-Intensity Laser Pulses to Optimize Ultrafast Heating of Atomic Clusters
M. J. V. Streeter, S. J. D. Dann, J. D. E. Scott +27
We describe how active feedback routines can be applied at limited repetition rate (5 Hz) to optimize high-power TW) laser interactions with clustered gases. Optimization of…
Evolution of dopant-induced helium nanoplasmas
S. R. Krishnan, Ch. Peltz, L. Fechner +13
Two-component nanoplasmas generated by strong-field ionization of doped helium nanodroplets are studied in a pump-probe experiment using few-cycle laser pulses in combination with…
Dopant induced ignition of helium nanodroplets in intense few-cycle laser pulses
S. R. Krishnan, L. Fechner, M. Kremer +13
We demonstrate ultrafast resonant energy absorption of rare-gas doped He nanodroplets from intense few-cycle (~10 fs) laser pulses. We find that less than 10 dopant atoms "ignite"…
A bright point source of ultrashort hard x-rays from laser bioplasmas
M. Krishnamurthy, Sudipta Mondal, Amit D. Lad +6
Micro and nano structures scatter light and amplify local electric fields very effectively. Energy incident as intense ultrashort laser pulses can be converted to x-rays and hot el…
Hot ion generation from nanostructured surfaces under intense, femtosecond irradiation
S. Bagchi, P. Prem Kiran, M. K. Bhuyan +4
We present the effect of a nanostructured surface on the emission of ions and electrons from intense (5-36 Petwatt per sq.cm) femtosecond laser produced plasmas. Electrons from opt…
Characterization of doping levels in heteronuclear, gas-phase, van der Waals clusters and their energy absorption from an intense optical field
J. Jha, P. Sharma, V. Nataraju +3
A simple mass spectrometric method has been developed to quantify dopant levels in heteronuclear clusters in the gas phase. The method is demonstrated with reference to quantificat…
