Pulse-duration dependence of saturable and reverse saturable absorption in ZnCo2O4 microflowers
Pritam Khan, Rajesh Kumar Yadav, Anirban Mondal +2
We employed open-aperture Z-scan technique to unveil the third-order optical nonlinearity in ZnCo2O4 (ZCO) microflowers. Our results indicate that intersystem crossing (ISC) lifeti…

Designing hybrid graphene oxide- gold nanoparticles for nonlinear optical response: Experiment and theory
Rajesh Kumar Yadav, J. Aneesh, Rituraj Sharma +6
Nonlinear optical absorption of light by materials are weak due to its perturbative nature, although a strong nonlinear response is of crucial importance to applications in optical…

Ultrafast light-induced softening of chalcogenide thin films above the rigidity percolation transition
Pritam Khan, Rajesh Kumar Yadav, K. V. Adarsh
Little is known about the role of network rigidity in light-induced structural rearrangements in network glasses due to a lack of supporting experiments and theories. In this repor…
