“…Only Zorenko et al [13,14] reported other technique such as liquid phase epitaxy for the growth of single crystalline films. To our knowledge, De la Fuente et al [15] produced for first time Nd-doped fibres of LSO and GSO in Ar+O2 atmosphere by the alternative Laser Floating Zone (LFZ) technique. Recently, pure GSO [16] and LSO [17] have been obtained for first time in air at high pulling rates employing this technique [16][17].…”

“…Furthermore, other approaches for oxyorthosilicates production have been employed during the last years using different methods, like pulsed laser deposition [42], sol-gel [43] or solid-state diffusional process [44]. On the other hand, their production by the LFZ technique is more recent [18,[45][46][47]; besides, there are two experiments performed in the 1980s decade by de la Fuente et al [33] and Black et al [34], who produced GdNdSiO 5 and 7Gd 2 O 3 •9SiO 2 :Nd materials applying a high laser power (~185 W).…”

“…These dopants are extensively used as emitting ions in several laser materials [4-6, 33, 34] produced by different crystallization methods. Indeed, de la Fuente et al [33] and Black et al [34] produced GdNdSiO 5 and 7Gd 2 O 3 •9SiO 2 :Nd single crystal laser materials by LFZ in Ar:O 2 atmospheres 30 years ago. However, most researchers employed standard growth methods.…”

This chapter reviews the laser floating zone (LFZ) technique, also known as the laser-heated pedestal growth (LHPG), focusing on the recently produced rareearth-doped oxyorthosilicate fibers. LFZ has been revealed as a suitable prototyping technique since high-quality crystals can be developed in short time with low consumption of precursor materials in a crucible-free processing that ensures to practically avoid by-products. Moreover, additional advantages are the possibility to treat and melt highly refractory materials together with the easy way for tailoring the final microstructural characteristics and this way the macroscopic physical properties. Thus, refractory rare-earth (RE) doped oxyorthosilicates following the formula RE 2 SiO 5 have been recently produced by the LFZ technique for tuning laser emission parameters. The oxyorthosilicates have high chemical stability and allow incorporation of many rare-earth ions yielding different applications, such as laser host materials, gamma ray detectors or scintillators, environmental barrier coatings (EBCs) and waveguides, among others. Thus, different kinds of oxyorthosilicates were produced by the LFZ technique, and the detailed effects of the main processing parameters on crystal's characteristics are discussed in this chapter.

“…Other related compounds, R 2 Si 2 O 7 , have been previously grown using optical FZ furnaces, however, the boules tended to have a high number of thermally generated cracks, and single grains isolated from the crystal boules were of relatively small sizes [54,55]. Previous studies [31,[56][57][58][59][60][61] have demonstrated the feasibility of the FZ technique using a laser floating zone furnace for preparing single crystals of relatively large size of members of the rare earth monosilicate family, Gd 2 SiO 5 , Nd x Gd 2−x SiO 5 and Lu x Gd 2−x SiO 5 (pure and Nd or Yb doped).…”

In recent years, rare earth silicate compounds have attracted the extensive attention of researchers owing to their potential for applications in scintillation crystals in gamma ray or X-ray detectors, as well as in thermal or environmental barrier coatings. Large high quality crystals of three members of the rare earth monosilicates family of compounds, R2SiO5 (with R = Dy, Ho, and Er), have been grown by the floating zone method, using a laser-diode-heated floating zone furnace. Crystal growths attempts were carried out using different parameters in order to determine the optimum conditions for the growth of these materials. The phase purity and the crystalline quality of the crystal boules were analysed using powder and Laue X-ray diffraction. Single crystal X-ray diffraction experiments were carried out to determine the crystal structures of the boules. The optimum conditions used for the crystal growth of R2SiO5 materials are reported. The phase purity and high crystalline quality of the crystals produced makes them ideal for detailed investigations of the intrinsic physical and chemical properties of these materials.
