Deskripsi
A high-quality Er<sup>3+</sup>-doped (Gd<sub>1−x</sub>Lu<sub>x</sub>)<sub>3</sub>Ga<sub>5</sub>O<sub>12</sub> (Er: LGGG) laser crystal with a size of <i>Φ</i> 36 × 45 mm<sup>3</sup> was successfully grown by the Czochralski (Cz) method for the first time. The effective segregation coefficient of Er<sup>3+</sup> was determined to be 0.97, close to 1, and, thus, the uniform high-quality Er: LGGG crystal can be grown. In addition, the thermal and spectroscopic properties of Er: LGGG were investigated. Based on the measured characteristics, the Er: LGGG crystal has a huge potential for use in the 3.0 µm mid-infrared laser because of its outstanding optical quality, extraordinary thermal conductivity and stable structure.
