Abstract

Faraday isolators (IF) are widely used in high-power fiber lasers in order to eliminate the detrimental influence of back reflections during the laser operation. One of the most widespread materials used for IF is a gallium-terbium garnet (TGG) crystal due to its appropriate magneto-optical properties. However, heating of magneto-optical crystals due to absorption of laser radiation deteriorates IF properties. Non-uniform heating leads to mechanical stresses and, therefore, to non-uniform polarization distortions [1]. Values of optical absorption coefficients of TGG greatly depend on a crystal growth technology [2]. Determination of the temperature dependence of optical absorption of TGG crystal was also one of the goals of this research.
