Abstract

We investigated the optical transverse pattern produced by counterpropagating two waves through a rubidium vapor cell in presence of a longitudinal magnetic field. A bistable behav­ior is observed. The optical switching process between two of these patterns is carried out us­ing three different mechanisms: mechanical closing of a pump beam, modulation of a pump beam intensity and modulation of additional beam intensity. A rapid switching of less than 10 μs between patterns can be carried out with a 2 μw power beam.
