Abstract

Cr³⁺:LiCaAlF₆ single crystals were grown by vertical Bridgman method from stoichiometric composition melt on our growth apparatus which was simple and easily operated. Boules were grown unseedly firstly and then along [1010] at 1 mm/h in a following atmosphere of Ar. The micro-defects in Cr³⁺:LiCaAlF₆ have been studied in detail with the help of x-ray diffraction, optical microscope, SEM, EDS and WDS. Heterogeneous micro-crystallites, inclusions of impurity particles and bubbles are found the main defects in the crystal. Traces of OH^- are found in the boules by infrared spectroscopy. The absorption and emission spectra of Cr³⁺ in LiCaAlF₆ are also presented.
