DYNAMICS OF A GAIN ANISOTROPIC OPTICALLY PUMPED LASER WITH ARBITRARY ANGLE BETWEEN LINEAR POLARIZATIONS OF PUMP AND LASER FIELDS

The dynamic behaviour of an optically pumped J = 0 double left right a rrow J = 1 double left right arrow J = 0 laser for any arbitrary value of the relative orientation angle between the linear polarizations of the pump and laser fields is analysed. By changing this angle, the st eady states show a smooth monotonic variation, but the dynamic states undergo a complex sequence of bifurcations, including a generalized cl ass of type-I intermittency that leads to the glueing of attractors. S mall variations in the polarization angle bring about structural attra ctor modifications as large as those produced by large variations in t he pump intensity.
