Potassium Terbium Fluoride Crystal Growth Development for Faraday Rotator Discs Fabrication, 6 July 1978--6 February 1979

摘要

Crystal growth experiments were performed and growth of KTb sub 3 F sub 10 crystals were accomplished. The crystal growth experiments consisted of hot zone modification and development of growth parameters. Several boules of KTb sub 3 F sub 10 30 to 40mm in diameter and one boule 50mm in diameter were grown at rates varying from .5mm/hr to 3.0mm/hr. The crystals evaluated display excellent optical quality. The optical path distortion was less than 0.5 fringe/cm at 633nm as viewed in Twyman--Green interferometry. Growth of large crystals has been limited by mechanical cleavage. (ERA citation 04:047990)
