LiNa₅Mo₉O₃₀: Crystal Growth, Linear, and Nonlinear Optical Properties

Abstract

We report on the crystal growth, linear and nonlinear optical properties of LiNa 5 Mo 9 O 30 . The refractive indices were measured, and a very large birefringence of 0.2545 at 450.2 nm was determined. In addition, calculated phase-matching curves indicate that LiNa 5 Mo 9 O 30 can achieve non-critical type I and type II phase-matching (NCPM) for incident 1064nm radiation. Maker-fringe measurements, to determine individual non-linear optical coefficients, were also performed on the crystals in d 31 = 1.4 pm/V, d 32 = 4.3 pm/V, and d 33 = 1.1 pm/V. The laser damage threshold (LDT) is around 1.2 GW/cm 2 at 1064 nm using a 6 ns Nd:YAG laser operating at 5The quality of the crystals were measured by high resolution x-ray diffraction rocking curve measurements that revealed a full width at half maximum (FWHM) of 59'' from the (001) reflection. The absorption edge was determined to be 357 nm, with transmission up to 5.26 µm. Our results indicate that single crystal LiNa 5 Mo 9 O 30 is an excellent polarizer as well as second-order nonlinear optical material.

Growth, Properties, and Theoretical Analysis of M2LiVO4 (M = Rb, Cs) Crystals: Two Potential Mid-Infrared Nonlinear Optical Materials

“…The results indicate that CLVO exhibits a very wide transmission range from 0.33 to 6.0 μm (Fig. 4a,b), compared to previously reported quaternary oxide crystals such as MgTeMoO 6 (0.36–5.2 μm) 29 , Cs 2 TeMo 3 O 12 (0.430–5.38 μm) 36 , Na 2 Te 3 Mo 3 O 16 (0.42–5.4 μm) 22, 37 , LiNa 5 Mo 9 O 30 (0.357–5.26 μm) 24 , β -BaTeMo 2 O 9 (0.5–5.0 μm) 38 , and Na 2 TeW 2 O 9 (0.36–5.0 μm) 39 . To evaluate the frequency doubling capabilities of RLVO and CLVO, SHG measurements were performed under a Q-switched Nd:YVO 4 laser ( λ  = 1064 nm) according to the Kurtz-Perry method 40 .…”

“…In recent research, many studies pay special attention to halides, iodates, molybdates, and vanadates since they normally exhibit large E g and diverse structural motifs so that it is possible to find materials with a subtle balance between large NLO efficiency and high LDT. A series of potential Mid-IR NLO crystals have been achieved, such as Pb 17 O 8 Cl 18 19 , α -AgI 3 O 8 and β -AgI 3 O 8 20 , RbIO 3 21 , Na 2 Te 3 Mo 3 O 16 22 , BaTeMo 2 O 9 23 , LiNa 5 Mo 9 O 30 24 , K 3 V 5 O 14 25, 26 and YCa 9 (VO 4 ) 7 27 . After a lot of screening and system performance evaluation, we think that Rb 2 LiVO 4 (RLVO) and Cs 2 LiVO 4 (CLVO) are good Mid-IR NLO materials.…”

Rb4Li2TiOGe4O12: A Titanyl Nonlinear Optical Material with the Widest Transparency Range

“…Hence, the search for new MIR NLO materials especially for high power laser applications, is an urgent and challenging task. Recently, several oxides e.g., La 3 SnGa 5 O 14 , Li 2 ZrTeO 6 , LiNa 5 Mo 9 O 30 , M 2 LiVO 4 (M=Rb, Cs), with basic crystallographic data and preliminary optical characterizations were reported and also proposed as new MIR NLO crystals.…”

A new barium-containing alkali metal silicate fluoride NaBa3Si2O7F with deep-UV optical property

“…The anionic structures depend on many factors, and the most important ones are: cationic size, valence, and electronegativity [29][30][31][32][33][34][35][36][37]. In terms of our research, the alkali and alkaline-earth metal atoms are ideal candidates, because there are no d-d or f-f electron transitions of the M−O (M means alkali or alkaline-earth metal atoms) bonds, which is beneficial to the transmission of UV light [37][38][39][40][41][42][43][44][45]. Additionally, introducing elements of halogen family may be an effective way to obtain better functional materials according to the previous report [46][47][48][49][50].…”
