“…Compared with LiNbO 3 (LN), LT has a lower Curie temperature and a higher photorefractive damage threshold (Foulon et al, 1995;Lee et al, 2005). However, because of the incongruent nature of LT, which results in the evaporation of Li 2 O, there are no reports to date on LT fibers < 800 mm in fiber diameter (Burlot et al, 1998). In this paper, we will first describe the fabrication of our small-diameter LT fiber such that electric-field poling is possible.…”

Lithium tantalate (LT) single‐crystalline fibers with various growth conditions were obtained using the laser‐heated pedestal growth (LHPG) method. The fibers can be produced with a diameter down to 70 µm and tens of centimetres in length by using different pulling rates. Preliminary experiments also showed that the LT fibers can be electrically poled for quasi‐phase matching. To facilitate wave propagation with low loss, glass‐clad LT fibers were fabricated by a co‐drawing LHPG method for the first time. A vacuum apparatus was developed to eliminate the bubbles from incongruent evaporation of lithium oxide during the drawing of the glass‐clad LT fibers. The glass‐clad fibers are classified into two different categories by the measurements of refractive index profiles. One is a step‐index fiber and the other is a graded‐index fiber. Both fiber types are multimode at present, but single‐mode LT fibers could be fabricated with the high‐precision control of the LHPG systems.

Li 2 O Evaporation During the Laser Heated Pedestal Growth of LiTaO 3 Single-Crystal Fibers.-The growth of fibers is performed using different pulling rates and growth atmosphere pressures. Fibers are produced with a diameter of about 800 µm and lengths between 20 and 50 mm. Due to the high melting point of LiTaO 3 , incongruent evaporation of lithium oxide takes place during the growth. The results indicate that the nil Li 2 O evaporation would be reached for pressures above 10-15 bars. -(BURLOT, R.; FERRIOL, M.; MONCORGE, R.; BOULON, G.; Eur. J. Solid State Inorg.
