We investigate coherent control of the two-photon transition pathways of a four-level atomic
system in a diamond configuration. When an ultrashort laser pulse interacts with this system …

Spectral features in two-dimensional Fourier transform optical spectroscopy were selectively
enhanced using pulse shapes and sequences designed to amplify specific excited-state …

It is well known that area pulses make Rabi oscillation and chirped pulses in the adiabatic
interaction regime induce complete population inversion of a two-state system. Here we …

Terahertz pulse shaping technique is used to adaptively design terahertz waveforms of
enhanced spectral correlation to particular materials among a given set of materials. In a …

We describe optimized coherent control methods for two-photon transitions in atoms of a
ladder-type three-state energy configuration. Our approach is based on the spatial coherent …

We have investigated multiphoton-ionization passages of rubidium atoms initiated from the
excited 5 P 3/2 energy state. For this we used coherent control schemes based on …

Photosynthesis process starts with light harvesting, where special pigment-protein
complexes absorb sunlight and transfer it in the form of electronic excitation to reaction …

We theoretically investigate the effect of the atomic densities N on propagation and spectral
property of femtosecond chirped Gaussian pulse in a three-level Λ-type atomic medium by …

Coherent control method steers a quantum system to a desirable final quantum state among
a number of final states otherwise possible in a given light-matter interaction, by using a …
