Investigations of the growth mechanism of stoichiometric LiNbO3 fibers grown by the laser-heated pedestal growth method

Laser Floating Zone Growth: Overview, Singular Materials, Broad Applications, and Future Perspectives

“…The optically transparent CaTa 2 O 6 single crystals were also grown by Almeida et al, in 2013 [81], exploring the three polymorphic modifications that this material exhibits at room temperature. Focusing on niobates, the production of promising optical active elements for lasers such as lithium niobates (LiNbO 3 ) [55,[82][83][84][85] or incongruent melting lithium-potassium niobate (K 3 Li 2−x Nb 5+x O 15+2x , KLN) [86][87][88] (Table 2) must be also high-lighted. In addition, more niobates were also grown by LFZ for holographic devices, as photorefractive materials by doping with Fe [89,90], for nonlinear optics and acoustic wave devices [91], for wavelength and frequency modulators [92,93], and, in the case of the EuNbO 4 , for optoelectronics as light emitters [94].…”

Characterization of the growth mechanism of YIG crystal fibers using the laser heated pedestal growth method

“…Thus, the YIG crystal growth mechanism could be evaluated by observing the composition and microstructure of the grown crystals. This basis has been successfully adopted to discuss the growth mechanism of LiNbO 3 [17]. We also wanted to grow YIG crystal fibers using Fe-rich solvent rod with the LHPG method that would have the same crystallographic orientation as that of the seed.…”

Properties of Ru-doped near-stoichiometric lithium niobate crystals produced by vapor transport equilibration

“…Kitamura et al [6] have reported that stoichiometric LN can be grown from a 58 mol% Li-rich melt by the continuouscharge double-crucible Czochralski method. Other methods can also be used to grow SLN crystals, such as the topseeded solution growth (TSSG) [7], flux [8], metal stripheated zone melting [9], laser-heated pedestal growth (LHPG) [10,11] method, and so on. In addition to the above-mentioned growth methods, another method to obtain SLN crystal samples is to convert CLN into SLN by the vapor transport equilibration (VTE) process.…”
