Temporal behavior of the velocity distribution function and the influence of collisions in laser cooling

Abstract

We present exact time-dependent solutions of the Fokker–Planck equation including the collisional term, which describes the influence of the laser field and collisions with the surrounding gas on the temporal behavior of the distribution function of cooled particles in the last stage of the cooling process. These solutions allow us to estimate the influence of collisions on the limiting temperature of free particles and trapped ions.
