The procedure of stimulated-Raman adiabatic passage (STIRAP), one of many well-
established techniques for quantum-state manipulation, finds widespread application in …

We review the theoretical status of intense laser induced orientation and alignment-a field of
study which lies at the interface of intense laser physics and chemical dynamics and having …

A pulse-shaping technique in the mid-infrared spectral range based on pulses with a super-
Gaussian temporal profile is considered for laser control. We show a realistic and efficient …

The efficiency of frequency up and down conversion of light in an atomic ensemble, with a
diamond level configuration, is analyzed theoretically. The conditions of pump field …

We study the stimulated Raman adiabatic passage technique in an N-pod system driven by
N pulsed fields when N-2 and N-1 pulses not connected to the initial state have the same …

We observed optical precursors in four-wave mixing based on a cold-atom gas. Optical
precursors appear at the edges of pulses of the generated optical field, and propagate …

We use density matrix theory to numerically simulate the orientation of LiH molecules
induced by laser pulses with two different envelope shapes. The results show that the …

Field-free molecular alignment is studied theoretically in presence of orienting laser pulse
and a delayed Infrared laser (IRL) pulse train. The pulse shapes taken are sine square (sin …

We investigate theoretically the rotational excitation and field free molecular orientation of
polar HBr molecule, interacting with train of ultrashort laser pulses. By adjusting the number …

Frequency conversion of single photons in a nonlinear crystal is theoretically discussed.
Losses and noise are included within a Heisenberg-Langevin formalism for the propagating …
