“…We used in our work the experimental set-up, which enables us to grow single crystal fibers with diameter 400-800 µm and the length up to 25 cm [4]. The fiber was pulled out by oriented seed crystal from the molten tip (pedestal) of a source rod (Fig.1).…”

“…The diameter of a molten zone smoothly varied from the source rod to the growing fiber. By special diffractive optical element [3,4] The technological requirements of crystal fiber growth demand that all parameters in the growth zone should be the same during the whole growth process. The system should be maintained in dynamic equilibrium.…”

“…The temperature distribution in the molten zone in the crystal fiber plays an important role in the process of single crystal fiber growth while using the laser heat pedestal growth (LHPG) technique [1,2,4]. In particular, the temperature distribution in the molten zone causes convective flows, which are responsible for the mass transfer processes.…”

“…One of the most LFZ-developed materials is single crystal Y 3 Al 5 O 12 (YAG) as a laser medium. Despite the fact that it was produced by Fejer et al in 1984 [25], a considerable amount of work has appeared during the last 20 years (Table 1) reporting its growth [35][36][37][38][40][41][42][49][50][51][53][54][55][56][57][58][59][60][61][62][63][64][65][66][67][68][69][70][71][72], improving the production efficiency [59,71], and also enhancing its mechanical and optical characteristics [38]. Among those studies, the work of Nie et al, in 2015 [37], who produced YAG single crystals doped with Er 3+ , Ho 3+ , Tm 3+ , Nd 3+ , and Yb 3+ may be highlighted here.…”

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

et al. 2020

The Laser Floating Zone (LFZ) technique, also known as Laser-Heated Pedestal Growth (LHPG), has been developed throughout the last several decades as a simple, fast, and crucible-free method for growing high-crystalline-quality materials, particularly when compared to the more conventional Verneuil, Bridgman–Stockbarger, and Czochralski methods. Multiple worldwide efforts have, over the years, enabled the growth of highly oriented polycrystalline and single-crystal high-melting materials. This work attempted to critically review the most representative advancements in LFZ apparatus and experimental parameters that enable the growth of high-quality polycrystalline materials and single crystals, along with the most commonly produced materials and their relevant physical properties. Emphasis will be given to materials for photonics and optics, as well as for electrical applications, particularly superconducting and thermoelectric materials, and to the growth of metastable phases. Concomitantly, an analysis was carried out on how LFZ may contribute to further understanding equilibrium vs. non-equilibrium phase selectivity, as well as its potential to achieve or contribute to future developments in the growth of crystals for emerging applications.

“…We used an experimental set-up based on the laser heated pedestal growth (LHPG) technique [20][21][22], which enabled us to grow single crystal fibers with a diameter of about 400-800 µm and a length of up to 25 cm [22]. The fiber was pulled by an oriented seed crystal from the molten tip (pedestal) of the source rod (Figure 1).…”

Facet Appearance on the Lateral Face of Sapphire Single-Crystal Fibers during LHPG Growth

et al. 2016

View full text Add to dashboard Cite

Abstract:Results of the study of the lateral surface of single-crystal (SC) sapphire fibers grown along crystallographic directions [0001] and 1120 by the LHPG method are presented. The appearance or absence of faceting of the lateral surface of the fibers depending on the growth direction is analyzed. The crystallographic orientation of the facets is investigated. The microstructure of the samples is investigated with the help of an optical microscope and a JSM-5910LV scanning electronic microscope (JEOL). The crystallographic orientations of the facets on the SC sapphire fiber surface are determined by electron backscatter diffraction (EBSD). The seed orientation is studied by means of XRD techniques.
