“…[26][27][28] One strategy for the synthesis of IR NLO crystals is to combine intrinsically non-centrosymmetric (NCS) moieties into the one crystalline material. Examples of such NCS moieties include transition-metal cations with d 0 electron configurations that are susceptible to second-order Jahn-Teller (SOJT) distortions (V 5+ , Ti 4+ , Nb 5+ , Mo 6+ , W 6+ , Ta 5+ ), [29][30][31][32][33] stereochemically-active lone-pair-containing cations (Pb 2+ , Bi 3+ , Sb 3+ , Sn 2+ ), 30,[34][35] and d 10 transition-metal ions with polar displacements (Zn 2+ , Cd 2+ , Cu + , Ag + ). [36][37][38] For example, the Sb 3+ cation possesses stereochemically-active lone-pair electrons and, as a result, tends to form asymmetric building units such as SbS 3 pyramids, SbS 4 "see-saw" polyhedra, SbS 5 square pyramids, or Sb 2 S 5 dimers, 39 while the Ag + cation (as a d 10 late-transition-metal ion) prefers to bond with sulfur.…”

Two interesting noncentrosymmetric metal chalcogenides, M 2 Ag 3 Sb 3 S 7 (M = Rb 1, Cs 2) were obtained by ionothermal synthesis. Crystals of compounds 1 and 2 are isostructural, consisting of two-dimensional (2D) anionic networks ¥[Ag3Sb3S7] 2with Rb + or Cs + cations located between the adjacent anionic layers. The optical band gaps of 1 and 2 are 2.11 and 2.02 eV, respectively. Second-harmonic generation (SHG) measurements revealed that 1 affords a phase-matching powder SHG response of ~0.5 × AgGaS2, while 2 exhibits a stronger SHG response of ~0.6 × AgGaS2 with type-I phase matchability. Both 1 and 2 possess wide transparency ranges (~0.6-20 μm), suggesting their potential as infrared (IR) nonlinear optical (NLO) materials. The laser damage thresholds (LDTs) of both 1 and 2 are about 2.3 times larger than that of AgGaS 2. The calculated birefringence indexes Δn are 0.1885 and 0.1944 at 1.064 μm, respectively, which are sufficiently large to achieve phase matching. Theoretical studies using density functional theory have been carried out to further understanding of the relationship between their NLO properties and band structures.

“…It is crucial for the applications that their thermal expansion possesses a weak anisotropy, although the crystals themselves have a 2 low symmetry and the thermal conductivity of BTMO decreases with increasing temperature [5]. These crystals also were applied to a diode-side-pumped actively Q-switched intracavity Raman laser generating at 1178 nm using Nd:YAG as a gain active medium and BTMO as the Raman source [6]. Applying a pump power of 115 W and pulse repetition rate of 10 kHz, a maximum first-Stokes output power of 1.9 W was achieved.…”

The Z-scan measurements for the non-centrosymmetric optical crystals β-BaTeMo 2 O 9 (BTMO) were performed. The corresponding experiments were carried out using the 5 ns pulses of the second harmonic of a nanosecond Nd:YAG laser at the 532 nm wavelength. It was shown that the studied crystals possess promising third-order optical susceptibilities, which allow to use the crystal as optical limiters. The comparison with other oxide materials is presented. To clarify the origin of the observed effect, the electronic and optical properties of BTMO were calculated using the density functional theory (DFT)-based method. The performed calculations of the electronic and optical properties revealed certain peculiar features that can be suitable for the non-linear optical applications. The relation between the observed nonlinear optical features and the calculated band structure is emphasized. The values of the calculated band gap and refractive index for β-BaTeMo 2 O 9 are also reported.

The second harmonic generation (SHG) and the first hyperpolarizability ( ijk β ) of β-BaTeMo 2 O 9 and α-BaTeMo 2 O 9 phases have been calculated. Due to structure arrangement and hence the orientation of the dipole moments, β-phase exhibit larger SHG than that of α-phase although it produces high local SHG. The linear optical properties reveals that α-phase show larger anisotropy between the optical components 2 ( 322 is the dominant tensor compound of α-phase with d 32 of about 0.11 pm/V. In addition, we have calculated the microscopic first hyperpolarizability, ijk β , the vector components along the dipole moment direction for the dominant components of β-BaTeMo 2 O 9 and α-BaTeMo 2 O 9 phases at static limit and at λ =1064 nm.
