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…
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)…
