Ab initio insights on the ultrafast strong-field dynamics of anatase TiO
Sruthil Lal S. B, Lokamani, Kushal Ramakrishna +5
Electron dynamics of anatase TiO under the influence of ultrashort and intense laser field is studied using the real-time time-dependent density functional theory (TDDFT). Our…
Study of a bi-axial (KTP) crystal using Double Stokes Mueller Polarimetry
Chitra Shaji, Sruthil Lal S B, Alok Sharan
We report the significance of the double Stokes Mueller polarimetry (DSMP) technique, to characterize a large size (3 X 3 X 5mm) KTP (Potassium titanyl phosphate) crystal. The crys…
Detection of excited state absorption cross-section of porphyrin through cw and femto-second laser pump-probe technique
A. Srinivasa Rao, Alok Sharan, N Venkatramaiah +1
We report on direct detection of excited states absorption cross-section using dual wavelength pump-probe technique. Also, we experimentally demonstrate using porphyrin composite m…
Third order nonlinear study of ZnO nano particles under femto-second laser illumination
A. Srinivasa Rao, Gayathri Sethuraman, Oriparambil Sivaraman Nirmal Ghosh +2
ZnO nano particles are synthesized at different percentages of Ag dopant by facile precipitation method. Two photon absorption (2PA) cross-section and nonlinear refractive index of…
Nonlinear Spectroscopic Study of Porphyrin Under cw and Femto-second Laser Pulse Excitation
A. Srinivasa Rao, Alok Sharan, N Venkatramaiah +1
Single Beam Transmittance (SBT) was used as nonlinear spectroscopic tool to investigate the absorption cross-sections and lifetimes of Tetra Phenyl porphyrin (H2TPP) and its OH- gr…
Spatial self-phase modulation in the H2TPP(OH)4 doped in Boric Acid Glass
Srinivasa Rao Allam, Mudasir H Dar, N Venkatramaiah +2
Self-diffraction rings or spatial self-phase modulation (SSPM) was observed in tetra-phenyl porphyrin derivative 5,10,15,20 - meso-tetrakis (4-hydroxyphenyl) porphyrin (H2TPP(OH)4)…
