Özet
The elastic light-light scattering below the threshold of the e+e- pair production leads to a variation in polarization of hard g-quanta traversing without loss a region where the laser light is focused. This effect can be used to control the g-quantum polarization. Equations are obtained which determine the variation of Stokes parameters of g-quanta in this case, and their solutions are given. It is pointed out that this effect can be observed in the experiment E-144 at SLAC. It should be taken into account and, perhaps, it can be used in experiments at future g g colliders.
