The Stokes Laser in the Different Pump Regimes

Xuan Khoa D., Van Lanh C., Hoai Son D., Quang Quy H.

Computational Methods in Science and Technology

2010

Vol. spec. iss. (2)

xx-xx

In is paper we present the set of dynamical equations of the Raman laser. The semi-classical theory in three-dimensional approach is of interest. The operating regime of the Stokes laser is investigated in some cases of the pumping rate.

Nonlinear Optics of Photons and Atoms

Long Van C., Xuan Khoa D., Trippenbach M.

Computational Methods in Science and Technology

2010

Vol. spec. iss. (2)

In this presentation we intend to focus on the exchange of experience between nonlinear optics (optical pulse and beam propagation in nonlinear media) and atom optics (dynamics of coherent waves generated from Bose-Einstein condensates). A common ground here is the nonlinear Schrödinger equation, which with the proper substitution of variables describes both types of phenomena. In nonlinear optics it is a light propagation equation that relates the signal at the end of the nonlinear crystal to the signal at the input face of the medium. In Bose-Einstein condensate dynamics it is the called the Gross-Pitaevskii equation. We will discuss various types of phenomena which have realisations both in the nonlinear optics and atom optics. We will concentrate our consideration on soliton formation, which is a challenge to fundamental and applied research in these two domains of physics.

In the framework of adiabatic approximation we perform numerical calculations of intensity distribution for the 4 1Product sign Leftwards arrow 1 1N-ary sumation+ band system of NaLi based on the Franck-Condon (FC) principle. Comparison between the calculated FC factors and the corresponding spectral lines observed recently reveals a good agreement. In addition, the internuclear distances at which the most favorable transitions occurred are caculated.
