Abstract

The bulk of the LiNa5Mo9O30 (LNM) crystals were successfully grown in the [010] and [001] directions without internal inclusions and cracks, using the Czochralski method with a low temperature gradient. The crystal grown in the [010] direction showed a tendency to twinning. The crystal grown in the [001] direction demonstrated high structural perfection (FWHM = 13″) for the (001) plane and high optical quality Δn ≈ 2 × 10−5. The laser-induced damage threshold was measured along a, b and c axes and was 12.2, 27.0 and 27.5 J/cm2, respectively. The thermo-optical coefficient dn/dT was measured for the main crystallographic axes, which was −5.75 × 10−6, −20.2 × 10−6 and 3.65 × 10−6 K−1 along the a, b and c axes, respectively. The second harmonic generation (SHG) was conducted in the crystalline LNM sample. The maximum efficiency value of 3.5% at a pump power of 12 W was achieved.

高光学质量 LiNa5Mo9O30 晶体的晶体生长

利用低温梯度的 Czochralski 方法，成功地在 [010] 和 [001] 方向上生长出了没有内部包裹体和裂纹的 LiNa5Mo9O30 (LNM) 晶体。在[010]方向生长的晶体出现了孪晶趋势。沿[001]方向生长的晶体在(001)平面上显示出较高的结构完美性（FWHM = 13″）和较高的光学质量Δn ≈ 2 × 10-5。沿 a、b 和 c 轴测量的激光诱导损伤阈值分别为 12.2、27.0 和 27.5 J/cm2。测量了主要晶轴的热光学系数 dn/dT，沿 a、b 和 c 轴分别为 -5.75 × 10-6、-20.2 × 10-6 和 3.65 × 10-6 K-1。在晶体 LNM 样品中进行了二次谐波发生（SHG）。在泵功率为 12 W 时，达到了 3.5% 的最大效率值。

期刊介绍： Crystals (ISSN 2073-4352) is an open access journal that covers all aspects of crystalline material research. Crystals can act as a reference, and as a publication resource, to the community. It publishes reviews, regular research articles, and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on article length. Full experimental details must be provided to enable the results to be reproduced. Crystals provides a forum for the advancement of our understanding of the nucleation, growth, processing, and characterization of crystalline materials. Their mechanical, chemical, electronic, magnetic, and optical properties, and their diverse applications, are all considered to be of importance.
