“…A three-level model [17] in semi-classical formalism, where the matter is treated in quantum mechanism and the laser field is described as a classical traveling wave, is quite adequate for these systems. The electric radiation field of the pump and probe beams are…”

“…The former term represents the σ + polarized component and the latter term represents the σ − one. Here 1 2 φ = 1 2 (φ P +φ S ) is the angle of rotation of the polarization ellipse and |1 − tan α|/(1 + tan α) is its axial ratio [33,34]. Thus, the desired final superposition of states ( 2) is controlled entirely by the polarization of the delayed pulse.…”

We discuss a simple scheme for preparing atoms and molecules in an arbitrary preselected coherent superposition of quantum states. The technique, which we call fractional stimulated Raman adiabatic passage (f-STIRAP), is based upon (incomplete) adiabatic population transfer between an initial state ψ1 and state ψ3 through an intermediate state ψ2. As in STIRAP, the Stokes pulse arrives before the pump pulse, but unlike STIRAP, the two pulses terminate simultaneously while maintaining a constant ratio of amplitudes. The independence of f-STIRAP from details of pulse shape and pulse area makes it the analog of conventional STIRAP in the creation of coherent superpositions of states. We suggest a smooth realization of f-STIRAP which requires only two laser pulses (which can be derived from a single laser) and at the same time ensures the automatic fulfillment of the asymptotic conditions at early and late times. Furthermore, we provide simple analytic estimates of the robustness of f-STIRAP against variations in the pulse intensity, the pulse delay, and the intermediate-state detuning, and discuss its possible extension to multistate systems.

“…is the angle of rotation of the polarization ellipse and |E 1 − E 2 |/(E 1 + E 2 ) is its axial ratio [30][31][32]34]. Measuring the superposition parameters in this manner, however, represents a two-dimensional optimization procedure which may be inconvenient, inefficient or inaccurate.…”

“…In the case when states ψ 1 and ψ 2 are the m = −1 and m = +1 magnetic sublevels of a J = 1 level and state ψ e is the m = 0 sublevel of a J = 0 or J = 1 level [28,29], this can be done by using a single elliptically polarized laser pulse, which can be seen as a superposition of two circularly polarized σ + and σ − pulses. The electric field of the elliptically polarized pulse in the complex representation E(t) = E x (t) + iE y (t) is given by [30][31][32]34]…”
