Title: Adiabatic squeezing of molecular wave packets by laser pulses

Abstract

Strong pulse sequences can be used to control the position and width of the molecular wave packet. In this paper we propose a new scheme to maximally compress the wave packet in a quasistatic way by freezing it at a peculiar adiabatic potential shaped by two laser pulses. The dynamic principles of the scheme and the characteristic effect of the different control parameters are presented and analyzed. We use two different molecular models, electronic potentials modeled by harmonic oscillators, with the same force constants, and the Na{sub 2} dimer, to show the typical yield that can be obtained in compressing the initial (minimum width) molecular wave function.
