? 2021 Elsevier B.V.A novel transparent Pr3+, Ce3+ co-doped terbium gallium garnet (Pr,Ce:Tb3Ga5O12, Pr,Ce:TGG) single crystal was grown by the Czochralski technique. Its transmittance is about 80% in 600～1300 nm wavelength range except for special absorption peaks. The Verdet constants (V) of Pr,Ce:TGG crystal at 532 nm and 632.8 nm are ?230 and ?153 rad T?1 m?1, which are both larger than those of terbium gallium garnet (Tb3Ga5O12, TGG) crystal. The thermal conductivity of Pr,Ce:TGG crystal is 3.35 W m?1 K?1 at 300 K. Bulk laser induced damage threshold (LIDT) of Pr,Ce:TGG crystal was measured to be 15 J cm?2 by R-on-1 test. The results show that Pr,Ce:TGG crystal as magneto-optical material has potential ability to be used in optical isolators.
