“…The micro-Raman spectrum obtained by focussing onto a grain of a typical thin film is presented in Fig. 3 together with the spectrum of a single crystal grown in our laboratory by Maillard et al using the Czochralski method [12]. Several 2 common peaks are observed at 599 cm − 1 , 622 cm − 1 and 637 cm − 1 , respectively, in addition to weak shoulders centred at 666 cm − 1 and 778 cm − 1 .…”

“…Preparation of Starting Material. Two varieties of starting materials were used to grow β-BBO single-crystal fibers: crystals 31 from previous Czoshralski growth produced in our laboratory 32 and powder synthesized by the solid-state carbonate method. 33 BBO powder is prepared from a stoichiometric mixture of boron oxide and barium carbonate (Fox-Chemicals 99.99%) ground in an agate mortar, placed in a platinum crucible, and slowly heated to 920 °C.…”

β-BBO single-crystal fibers with dimensions up to 15 mm in length and 0.7 mm in diameter devoid of cracks and inclusions were successfully grown by the micro-pulling-down (μ-PD) method directly from a supercooling stoichiometric composition of BBO bath. The suitable pulling rate was 0.1 mm/min. Different morphologies of β-BBO fibers were observed using single-crystal seeds oriented along the c-axis, a-axis perpendicular to c-axis, and phase-matching directions θ = 22.8°and θ = 47.7°. Strong axial thermal gradients were applied throughout the growth and adjusted for each crystallographic direction. The effects of capillary dimensions on fiber quality were studied. The quality and orientation of the fibers were examined by Raman spectroscopy and polarizing microscopy. The ultraviolet (UV) absorption edge of β-BBO single-crystal fibers was measured at 200 nm. A type I second-harmonic generation was produced with a continuous Nd:YAG laser at 1064 nm on β-BBO fibers oriented according to the phase-matching direction.
