Powerful Lasers for High Energy Density Physics

“…The amplifying system is built on the basis of pulse elongation with the use of diffraction gratings to a nanosecond duration, amplification, and further compression to the initial form (with retention of the spectral form of radiation after amplification) [36]. At the Institute of Applied Physics, Russian Academy of Sciences, the parametric light conversion method [37] was proposed for the creation of complexes with such a pulse power. A radiation pulse is amplified in a nonlinear anisotropic crystal due to the transfer of energy from a pumping wave, and, as a result, an idler wave is also generated.…”
