Three-State Model for Laser-Assisted Collisions

Abstract

A laser assisted collision (LAC) is one involving a combined collisional-radiative interaction. A typical laser assisted collision can be written as a reaction of the form. A sub I + h-bar omega yields A sub F, where I> and F> are composite initial and final states, respectively, of atoms A and A' which are undergoing the collision, and Omega is the frequency of the laser field which produces the transition from initial to final state. The eigenkets I> and F> may be expressed in terms of the individual atomic-state eigenkets as I> = i> i'>, F> = f> f'>, where unprimed states refer to atom A and primed states refer to atom A'. Laser-assisted collisions have been classified into two broad categories. First, there are the so-called optical collisions (1) or Collisionally-Aided Radiative Excitation (CARE)) (2) involving reactions of the form. Second, there are the so-called radiative collisions or Laser-Induced Collisional Excitation Transfer ( LICET ) or Radiatively-aided Inelastic Collisions (RAIC). Reprints. (JHD)
