Abstract

Lithium tetraborate crystals have great demand due to its non‐critical phase matching at 90Β°. Transparent and good optical quality single crystals of undoped and Mn doped Li~2~B~4~O~7~ were grown by Czochralski technique in air atmosphere. The crystalline phase was determined by X‐ray diffraction. Doping of Mn in the grown crystals was confirmed by energy dispersive analysis of X‐rays (EDAX) technique. Transmission spectra show that the crystal is transparent in the visible region. Birefringence interferograms were recorded to qualitatively analyse the optical homogeneity of the grown crystals and to quantify the birefringence of the samples in desired crystal direction.

Pure and Co-doped Li 2 B 4 O 7 (LBO) single crystals were grown by the Czochralski method. Starting concentrations of Co 2 O 3 in the melt were: 0.5, 0.85 and 1 mol% relative to Li 2 CO 3 . Technological factors affecting the quality of both crystals were discussed. Optical absorption and EPR spectr
