Faraday isolator for high-power nonpolarized radiation

We propose a Faraday isolator scheme in which high-power nonpolarized radiation is divided into two orthogonally polarized beams that pass through one MOE. The experimentally confirmed advantage of the scheme is reduction of thermally induced depolarization due to mutual thermal action of the beams optimally spaced apart. The advantage in the level of thermally induced depolarization over conventional schemes is up to 60%.
