Crystal Growth, Thermal and Spectral Properties of Er: LGGG Crystal

A high-quality Er -doped (Gd Lu ) Ga O (Er: LGGG) laser crystal with a size of 36 × 45 mm was successfully grown by the Czochralski (Cz) method for the first time. The effective segregation coefficient of Er was determined to be 0.97, close to 1, and, thus, the uniform high-quality Er: LGGG crystal...

Description
Summary:A high-quality Er -doped (Gd Lu ) Ga O (Er: LGGG) laser crystal with a size of 36 × 45 mm was successfully grown by the Czochralski (Cz) method for the first time. The effective segregation coefficient of Er 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.
