Summary:A Faraday isolator (FI) with depolarization compensation using a counterrotation scheme has been realized in experiment for the first time, to the best of our knowledge. It is based on terbium scandium aluminum garnet crystals with negative optical anisotropy parameters. An order of magnitude advantage over the traditional FI scheme is achieved in this case. An isolation ratio of 35.7 dB at a radiation power of 1440 W has been obtained. According to the numerical estimates, an isolation ratio of 30 dB can be provided up to a power of 5.5 kW.
