Abstract: As growing ε-GaSe single crystal, volatile component and curving solidification interface spoil the qualities of crystals. The GaSe single crystal in Φ19 mm×65 mm size was grown by modified vertical Bridgman method. The crystallinity and optical properties of as-grown crystals were measured by XRD and transmission spectra, respectively. The FT-IR measurements indicated wide transparency over the spectral range (0.65-16 μm) and low absorption coefficient (<0.3 cm-1) in grown GaSe crystal.

Key words: Bridgman technique, nonlinear optical crystal, solidification interface
