KORNEEV, N.; TORRES, Y.M.  and  ORTEGA, Y.. Enhancement of vectorial nonlinearity in rubidium vapor by using an additional pump beam. Rev. mex. fis. [online]. 2014, vol.60, n.5, pp.366-370. ISSN 0035-001X.

We report the enhancement of nonlinearity to absorption ratio in rubidium vapor for a signal beam in ⁸⁷Rb transition D2 line with F_g = 1 by means of an additional pump beam. Experimental results for a pump beam in co- and counter-propagation configurations are reported. The ratio increment of approximately 2 times is obtained for the co-propagating case when the pump beam is tuned at F_g = 1.

Keywords : Rubidium vapor; polarization self-rotation; nonlinear phase shift.
