Observation of ultrafast laser-plasma evolution by pump-probe reflectometry and Doppler spectrometry

Autor: Adak, Amitava, Singh, Prashant Kumar, Lad, Amit D., Chatterjee, Gourab, Kumar, G. Ravindra

We demonstrate pump-probe techniques, namely the Doppler spectrometry and the reflectometry in detail, which directly capture the time-resolved ultrafast evolution of high intensity femtosecond laser-driven hot, dense plasma. These techniques are cap

Operation regimes, gain dynamics and highly stable operation points of Ho:YLF regenerative amplifiers

Autor: Kroetz, Peter, Ruehl, Axel, Calendron, Anne-Laure, Chatterjee, Gourab, Cankaya, Huseyin, Murari, Krishna, Kaertner, Franz X., Hartl, Ingmar, Miller, R. J. Dwayne

We present a comprehensive study of laser pulse amplification with respect to operation regimes, gain dynamics, and highly stable operation points of Ho:YLF regenerative amplifiers (RAs). The findings are expected to be more generic than for this spe

Overcoming Bifurcation Instability in High-Repetition-Rate Ho:YLF Regenerative Amplifiers

Autor: Kroetz, Peter, Ruehl, Axel, Chatterjee, Gourab, Calendron, Anne-Laure, Murari, Krishna, Cankaya, Huseyin, Li, Peng, Kaertner, Franz X., Hartl, Ingmar, Miller, R. J. Dwayne

We demonstrate a Ho:YLF regenerative amplifier (RA) overcoming bifurcation instability and consequently achieving high extraction energies of 6.9 mJ at a repetition rate of 1 kHz with pulse-to-pulse fluctuations of 1.1%. Measurements of the output pu

High-resolution measurements of the spatial and temporal evolution of megagauss magnetic fields created in intense short-pulse laser-plasma interactions

Autor: Chatterjee, Gourab, Singh, Prashant Kumar, Adak, Amitava, Lad, Amit D., Kumar, G. Ravindra

A pump-probe polarimetric technique is demonstrated, which provides a complete, temporally and spatially-resolved mapping of the megagauss magnetic fields generated in intense short-pulse laser-plasma interactions. A normally-incident time-delayed pr

Micron-Scale Mapping of Megagauss Magnetic Fields in Petawatt Laser-Solid Interactions

Autor: Chatterjee, Gourab, Singh, Prashant Kumar, Robinson, A. P. L., Booth, N., Culfa, O., Dance, R. J., Gizzi, L. A., Gray, R. J., Green, J. S., Koester, P., Kumar, G. Ravindra, Labate, L., Lad, Amit D., Lancaster, K. L., Pasley, J., Woolsey, N. C., Rajeev, P. P.

We report spatially and temporally resolved measurements of magnetic fields generated by petawatt laser-solid interactions with high spatial resolution, using optical polarimetry. The polarimetric measurements map the megagauss magnetic field profile
