Ultrafast Dynamics of Gold Nanorods: Tuning between Photo-Bleaching and Photo-Induced Absorption
M. Anija, Sunil Kumar, N. Kamaraju +3
We report ultrafast electron dynamics in gold nanorods investigated using 80 fs laser pulses centered at 1.57 eV. Five types of nanorod colloidal suspensions in water having their…

Large-amplitude chirped coherent phonons in tellurium mediated by ultrafast photoexcited carrier diffusion
N. Kamaraju, Sunil Kumar, M. Anija +1
We report femtosecond time-resolved reflectivity measurements of coherent phonons in tellurium performed over a wide range of temperatures (3K to 296K) and pump laser intensities.…

Femtosecond carrier dynamics and saturable absorption in graphene suspensions
Sunil Kumar, M. Anija, N. Kamaraju +4
Nonlinear optical properties and carrier relaxation dynamics in graphene, suspended in three different solvents, are investigated using femtosecond (80 fs pulses) Z-scan and degene…
