Rb8Nb10Ge6O41: a new niobium-germanate crystal featuring unique one-dimensional [Nb7O30]∞ chains and wide mid-IR transparency

“…11 Notably, germanate-based materials inherently possess potential for applications in both linear and nonlinear optics, due to their extensive visible and infrared transmittance range, as well as impressive thermal and chemical stability. 12–14 For instance, through the rational integration of customized functional motifs comprising antiparallel [GeO 4 ] tetrahedra and distorted [NbO 6 ] octahedra, the Cs 3 Nb 5 GeO 16 crystal not only demonstrates a wide transparent window but also achieves a breakthrough of experimental birefringence of 0.19 @532 nm among the available germanate oxides, signifying its significant potential for manipulating polarized light. 15 Recently, Ye et al have reported findings on a niobium germanate oxide, 16 K 3 Nb 3 Ge 2 O 13 , which showcases [GeO 4 ] units and distinctive [Nb 3 O 12 ] ∞ tubular chains constructed by circular [Nb 3 O 15 ] tripolymers.…”

Two Acentric Zn-Based l-Tartrates with Moderate Second Harmonic Generation Responses and Large Birefringence

“…Based on the second harmonic generation (SHG) effect of NLO crystals, it is easier to realize the solid-state and miniaturization of laser devices. Over the past few decades, the popularization of laser application in increasing scenarios has stimulated enthusiasm for the development of more novel NLO crystals. − …”

VTe2: Broadband Saturable Absorber for Passively Q-Switched Lasers in the Near- and Mid-Infrared Regions

“…58 Very recently, the potential nonlinear optical material, vanadium tellurate (LiVTeO 5 ), was created through the combination of Te 4+ cations and V 5+ cations. 59 While, until now, only NbTe 2 and TaTe 2 have been investigated as SAs in mode-locked fiber lasers and PQS solid-state lasers, respectively. Experimentally, Zhang et al 60 and Shang et al 61 investigated the nonlinear optical properties in a mode-locked fiber laser with NbTe 2 −PVA film SA as the mode-locked device and proved that NbTe 2 demonstrates as a broadband SA to produce mode-locked pulses within fiber lasers.…”
