Nonlinear Optical Limiting with Hybrid Nanostructures of NiCo2O4 and Multiwall Carbon Nanotubes
Ankit Sharma, Pritam Khan, Mansi Pathak +2
Nonlinear optical (NLO) response in terms of reverse saturable absorption (RSA) has been exploited extensively for optical limiting. Here, we experimentally demonstrate that flower…
Unveiling and engineering of third order optical nonlinearities in NiCoO nanoflowers
Ankit Sharma, Pritam Khan, Dipendranath Mandal +3
In this paper, we demonstrate NiCoO (NCO) as an efficient new nonlinear optical material with straightforward potential applications in optical limiting devices. We obtain…
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…
Role of thermal and photo annealing on nonlinear optical response of Ge30Se55Bi15 thin films
Adyasha Aparimita, Pritam Khan, J. R. Aswin +2
In this article, we employed nanosecond Z-scan technique to demonstrate the nonlinear optical response in Ge30Se55Bi15 thin films after thermal and photo annealing. The intensity d…
Ultrafast Light-driven Simultaneous Excitation of Coherent Terahertz Magnons and Phonons in Multiferroic BiFeO
Pritam Khan, Masataka Kanamaru, Keita Matsumoto +2
The ultrafast switching of magnetization in multiferroic materials by a femtosecond laser could provide various advantages in photonics and magnonics. An efficient approach to cont…
Near resonant nanosecond laser driven nonlinear optical response in As50S50 thin films
Dipendranath Mandal, Pritam Khan, K. V. Adarsh
Nanosecond near resonant excitation in As50S50 thin films leads to strong nonlinear optical response, i.e. nonlinear absorption coefficient up to 4 x 106 cm/GW and nonlinear refrac…
