Novel Faraday Rotator by Use of Cryogenic TGG Ceramics

We have proposed the cryogenic TGG ceramics based Faraday rotator for High peak and high average power laser. As the first demonstration of Faraday effect in a TGG ceramics, its Verdet constant at 1053 nm is evaluated to be 36.4 rad/Tm at room temperature which is same as that of the single crystal....

Zusammenfassung:We have proposed the cryogenic TGG ceramics based Faraday rotator for High peak and high average power laser. As the first demonstration of Faraday effect in a TGG ceramics, its Verdet constant at 1053 nm is evaluated to be 36.4 rad/Tm at room temperature which is same as that of the single crystal. In addition, the temperature dependence of Verdet constant is obtained experimentally. At liquid helium temperature, it is 87 times greater than that at room temperature. The measured thermal conductivity was corresponding to TGG single crystal.
