We have introduced a new concept for a polarization-resistant (PR) adaptive interferometer utilizing the orthogonal geometry of vectorial two-wave mixing in a gyrotropic photorefractive crystal. We have developed a mathematical model to calculate the efficiency of two-wave mixing in gyrotropic crystal under orthogonal geometry. By applying this model, we have identified the conditions necessary for achieving a PR-mode in the adaptive interferometer. Our research demonstrates that the polarization independence mode is achievable due to the natural rotation of the polarization plane of light waves in the crystal caused by optical gyrotropy. A key advantage of this approach is the ability to achieve PR-mode using only a single reference wave, as opposed to other techniques that require two reference waves. This results in a significant simplification of the PR-adaptive interferometer setup. The research was funded by the Russian Science Foundation (Project. No. 24-22-00413).
