Separation of Isotopes via Dynamical Delocalization

“…Above the critical modulation λ c (= √ η/2), we can find quantum delocalization. [7,8] For two different isotopes of mass m 1 and m 2 = m 1 + ∆m, two different critical modulation strengths occur, i.e. λ = λ c1 for atoms of mass m 1 and λ = λ c2 for atoms of mass m 2 .…”

“…[5] Laser-induced isotope separation is realized experimentally. [7] It is shown that isotopes are easily separated by controlling their evolution in Fermi accelerator. [8] In order to study evolution of atoms on the atomic mirror, the trap is switched off and the super cooled atoms move towards the mirror under influence of the gravitational field.…”

Laser beam propagation in nonlinearly absorbing media

“…It has been believed that the latter does not propagate in a mode that maintains its shape (intensity distribution function), and must be reshaped regularly to combat this problem. Thus beam delivery systems for applications in which long path lengths are needed (e.g., laser isotope separation) have traditionally been achieved with Gaussian beams using multiple pass cells of the Herriot design 1,2,3 . In this work it is shown that the absorption profile of the medium plays a very important role in determining the propagation characteristics of the laser beam in the medium.…”
