A cryogenic Faraday isolator based on terbium-gallium garnet (TGG) ceramics has been designed and studied in experiments. Its performance capabilities at the laser radiation power of 435 W are demonstrated, and our models suggest that the isolator sh

The thermal lens magneto-active CeF3, KTb3F10 and Na0.37Tb0.63F2.26 fluorides was investigated by the phase-shift interferometry technique. It was shown that the fluorides introduce a much weaker thermal lens into the laser beam than a traditional TG

We describe a cryogenic Faraday isolator with a gadolinium gallium garnet (GGG) crystal used for the first time as a magneto-optic element. Simultaneous compensation of thermally induced depolarization and thermal lensing using FK51 glass is demonstr
