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…
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…
Quantification of nonlinear absorption in ternary As-Sb-Se chalcogenide glasses
P. Pradhan, Pritam Khan, J. R. Aswin +4
In this article, we studied intensity dependent third order nonlinear optical response in ternary As40Sb7Se53 and As40Sb10Se50 chalcogenide glasses by employing nanosecond Z-scan t…
