“…31 Therefore, these sulfide NLO materials have been used in infrared applications but may not be useful for 1.064-µm laser applications due to their low energy band gap. The strong SHG intensity from Zn x Ba 2 B 2 S 5+x (x ≈ 0.2) indicates that this phase may be useful for both 1.064 µm and large wavelength infrared application.…”

Thioborate materials have been considered for novel infrared nonlinear optical (NLO) materials having large optical nonlinear properties combined with favorable laser damage thresholds and wide transmission ranges from the visible to the mid-infrared regions. In this work, known and new thioborate materials have been investigated that have the potential to overcome the low laser damage thresholds of the NLO chalcopyrite sulfide materials such as AgGaS2 without losing their large nonlinear properties and wide transmission ranges. A new thioborate phase, polycrystalline ZnxBa2B2S5+x (x ≈ 0.2), has been prepared by the reaction of the metal sulfides and B2S3 glass in carbon crucibles sealed inside evacuated silica tubes. It crystallizes in the tetragonal system with unit cell parameters of a = 4.762(4) Å and c= 24.020(7) Å and is based on isolated (BS3)3-structural units. The second harmonic generation (SHG) efficiency determined on powders of ZnxBa2B2S5+x (x ≈ 0.2) is 50 times larger than that of α-SiO2. The infrared spectrum shows transparency from 2.5 to 10 μm with absorption bands around 12 μm related to the vibration modes of (BS3)3-units. The UV−visible spectrum shows that it is transparent in the visible region down to 350 nm, which is a large improvement over the absorption edge of AgGaS2 at 490 nm. ReceiVed September 27, 2004.

The second harmonic generation (SHG) efficiency determined on powders of Zn x Ba 2 B 2 S 5+x (x ≈ 0.2) is ∼50 times larger than that of R-SiO 2. The infrared spectrum shows transparency from 2.5 to 10 µm with absorption bands around 12 µm related to the vibration modes of (BS 3 ) 3-units.

“…Most of these contain the heavier alkali metals Cs, Rb, or K. Although it is more difficult to obtain chalcogenides containing the lighter alkali metals Na or Li by this method some have been synthesized. Examples include LiAuS [3], Li 3 AuS 2 [3], Li 4 GeS 4 [4], Li 0.5 Pb 1.75 GeS 4 [5], LiEuPSe 4 [6], Li 2 PbGeS 4 [7], Li 2 EuGeS 4 [7], Na 8 Pb 2 Ge 4 S 12 [8], Na 6 Pb 3 (PS 4 ) 4 [9], Na 1.5 Pb 1.75 GeS 4 [5], and Na 1.5 Pb 0.75 GeS 4 [5].…”

“…This nonlinear behavior was observed for several related compounds with the same structure. For instance, irradiation of a Na 0.5 Pb 1.75 GeS 4 powder sample with a 3.5 mm laser yields a strong SHG signal that was 7-8 times greater than that of similarly prepared LiNbO 3 powder samples [10]. HT a-Pb 2 GeS 4 and Pb 2 GeSe 4 produced weak SHG responses (about 20% that of quartz) under irradiation with 1064 nm laser light [11].…”
