Scattering defect in large diameter titanium doped sapphire crystal grown by Kyropoulos technique.

Abstract

The Kyropoulos technique allows growing large diameter Ti-doped sapphire for Chirped Pulse Amplification CPA laser. A scattering defect particular to Kyropoulos grown crystal is presented. This defect is characterized by different techniques: luminescence, absorption measurement, X-ray rocking curve, Transmission electron microscopy measurements. The impact of this defect to the potential application in CPA laser is evaluated. The nature of this defect is discussed. Modified convexity of the interface is proposed to avoid the formation of this defect and increase the quality of the Ti-doped sapphire crystal.
