Research Abstract

Sapphire single crystals were irradiated with femtosecond laser pulses to form defects inside and the defects were characterized using various methods in detail. The single crystals containing defects were annealed at 1200～1500℃ in air and their morphology change was observed. In addition, the sapphire sample containing defects were embedded inside the chromium oxide powder compact and annealed to promote the diffusion from the surface into inside.
