fabrication and characterizations of a erbium doped terbium gallium garnet crystal for Faraday Rotators
Materials Letters, 2015Co-Authors: Zhe Chen, Xiangyong Wang, Lei Yang, Jun Wang, Yin HangAbstract:Abstract High optical (Tb (1− x ) Er x ) 3 Ga 5 O 12 (TEGG) single crystal has been grown by the Czochralski (Cz) technique. X-ray powder diffraction was carried out and lattice parameters were calculated, which showed that the single crystal belongs to cubic crystal system with high crystallinity. Observed optical characteristics and magneto-optical properties were compared with those of pure terbium gallium garnet (TGG) crystal at room temperature. The Verdet constant ( V ) dispersion of TEGG was evaluated in the visible and near-infrared region (VIS–NIR). The V of TEGG at 532 nm comes up to 224.5 rad m −1 T −1 , obviously larger than that of TGG. The high thermal conductivity and laser induced damage threshold (LIDT) of TEGG further confirmed its great potential to be applied in the high power laser system.

highly transparent terbium gallium garnet crystal fabricated by the floating zone method for visible infrared optical isolators
Optical Materials, 2015Co-Authors: Zhe Chen, Xiangyong Wang, Lei Yang, Jun Wang, Yin HangAbstract:Abstract Highly transparent terbium gallium garnet (Tb 3 Ga 5 O 12 ; TGG) single crystal having a large Verdet constant based on the visible and near-infrared region (VIS–NIR) Faraday rotator was grown by Floating Zone (FZ) growth machine. We successfully grew TGG single-crystal rods of 8–10 mm in diameter, which was suitable for the use in optical devices. The crystal showed a full-width at half-maximum as little as 18 arcsec by the X-ray rocking curve measurement. The Faraday rotation ( B = 0.55T) was investigated at wavelength of 532, 632.8, 1064 nm at room temperature. The lower weak absorption coefficient, higher Verdet constant, thermal conductivity and laser induced damage threshold (LIDT) compared to the commercial TGG gives the great potential of using this new method to meet the increasing demand of VIS–NIR Faraday Rotators (FRs).

great enhancement of Faraday effect by pr doping terbium gallium garnet a highly transparent vi ir Faraday rotator
Materials Letters, 2015Co-Authors: Zhe Chen, Jiaqi Hong, Peixiong Zhang, Yin Hang, Xiangyong Wang, Lei Yang, Yaqi WangAbstract:Abstract A highly transparent (Tb (1− x ) Pr x ) 3 Ga 5 O 12 (TPGG) single crystal was grown by the Czochralski (Cz) method. The grown crystal was characterized by x-ray diffraction analysis which showed the crystal belongs to cubic structure with high crystallinity. The optical and magneto-optical properties of TPGG are analyzed in detailed and its figure of merit as Faraday rotator has been determined at room temperature. The Verdet constant of TPGG at 632.8 nm was −182.43 rad m −1 T −1 , which is 36.14% larger than that of terbium gallium garnet (TGG). The thermal conductivity and laser induced damage threshold (LIDT) of the TPGG were also measured. Overall, the TPGG single crystal studied here exhibits superior properties than the commercial TGG so far, therefore it has potential to cover the increasing demand for new and improved Faraday Rotators in the VI-IR region.

uv visible Faraday Rotators based on rare earth fluoride single crystals liref_4 re tb dy ho er and yb prf_3 and cef_3
Optics Express, 2012Co-Authors: V Vasyliev, Encarnacion G Villora, Masaru Nakamura, Yoshiyuki Sugahara, Kiyoshi ShimamuraAbstract:High optical quality LiREF4 (RE = Tb3+, Dy3+, Ho3+, Er3+ and Yb3+), PrF3 and CeF3 single crystals have been grown by the Czochralski technique. Their magneto-optical properties have been measured and analyzed in detail in the ultraviolet-visible wavelength region, and their figures of merit as Faraday Rotators have been determined. CeF3 presents superior properties above 300 nm, showing a figure of merit higher than that of the reference material, terbium-gallium-garnet, which is nowadays used in the visible-near infrared. PrF3 is the best rotator for the 220-300 nm range. Towards shorter wavelength and in the vacuum ultraviolet, it is shown that the LiREF4 crystals are unique Rotators. Overall, the rare-earth fluoride single crystals studied here exhibit better properties than other materials considered so far, and therefore they have potential to cover the increasing demand for new and improved Faraday Rotators in the ultraviolet-visible wavelength region.

cef 3 and prf 3 as uv visible Faraday Rotators
Optics Express, 2011Co-Authors: P Molina, V Vasyliev, Encarnacion G Villora, Kiyoshi ShimamuraAbstract:CeF3 and PrF3 single crystals are investigated as Faraday Rotators for the UV-visible region. Their properties are compared with those of the industrial standard reference terbium-gallium-garnet (TGG) single crystal. In contrast to TGG, CeF3 exhibits a higher transparency in the whole near UV-visible-IR, and a remarkable higher figure of merit which rapidly increases towards the cutoff. In the case of PrF3, the transparency extends to even shorter wavelengths, and analogously to CeF3 its figure of merit increases notably in the UV. These results indicate the potential of CeF3 and PrF3 as optical isolators in the UV-visible, where at present there are no alternative candidates.
