Zusammenfassung: 
In this contribution we report on two examples of mirrorless oscillation in photorefractive BaTiO(3) pumped by two pairs of two counterpropagating light waves, each of them containing an ordinary and an extraordinary component of polarization. The oscillation waves are located on a cone with an apex angle defined by the phase matching conditions for this wave mixing process. The threshold behaviour is investigated by measuring the dependence of oscillation efficiency and starting time on the intensity ratio of the orthogonal polarized components of the pump beams.
