“…To measure the tuning curve of its second harmonic generation (SHG), the testing IR light source was a grazing-incidence optical parametric oscillator based on QPM PPLN crystal [3]. The pump laser was operated at 4 kHz with a pulse duration of 27 ns and a continuous wavelength tuning range from 1400 to 1600 nm.…”

“…In this paper, an in-situ periodically poled Lithium Tantalate crystal fiber (PPLTCF) was first demonstrated. Biasing electrodes were used in the LHPG growth chamber to enable the poling process [3]. Compared to the poling of Lithium Niobate (LN) crystal fiber, the electrode position has to be located well above the LT molten zone because of the large difference of Curie temperature between LN and LT, as shown in Fig.…”

“…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]. Following the production of laser garnets, gadolinium-and gallium-based compositions have also been produced during the last several years.…”

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.

“…It has also been pulled into crystal fiber so that the required material consumption can be reduced [15]. A PPLN crystal fiber sample with a domain pitch of 15.45 m was fabricated by an in situ electric-fieldinduced microswing poling technique during crystal fiber growth by the laser-heated pedestal growth (LHPG) method [16]. The cascaded SHG and SFG scheme has the advantage of easy coupling [17].…”

Using a novel self-cascaded first-order second-harmonic generation (SHG) and third-order sum-frequency generation (SFG) in a ZnO periodically poled lithium niobate crystal fiber, tunable blue-green light was demonstrated. At a domain pitch of 15.45 m, the SHG signal and its fundamental signal at 1423.9 nm can satisfy the third-order SFG quasi-phase-matched (QPM) condition. The measured SHG power at 714.2 nm was 12.25 mW under 100 mW input power, and the estimated nonlinear coefficient ͑d 33 ͒ achieved was 25.3 pm/ V. The selfcascaded SHG+ SFG power measured at 477.1 nm was ϳ700 W under 350 mW input power. The maximum internal efficiency of the SHG is 14.84%. The tuning range of the self-cascaded SHG and SFG generated tunable blue-green light was more than 40 nm, from 471.3 to 515 nm. The maximum simulated 3 dB bandwidth achieved using a gradient-period QPM structure is 196 nm, which is from 1476 to 1672 nm. The gainbandwidth product of the self-cascaded SHG and SFG processes decreases drastically as the bandwidth is broadened.
