| dc.description.abstract | Energy dependent evolution of Stokes and anti-Stokes lines of ice VII via forward stimulated Raman scattering (FSRS) during propagation of a 30 ps laser pulse through liquid water, confirming structural change over GPa pressure range, is studied. Self-focusing of the intense laser pulses is observed to ionize the medium generating free electrons that dominate the evolution of SRS signals. The confinement of plasma-generated free electrons by filamentation is observed to enhance the signature Raman modes of ice VII by reducing the SRS threshold. | |
