Roadmap on nonlinear optics–focus on Chinese research

Publikováno v: JPhys Photonics, Vol 5, Iss 3, p 032501 (2023)

In nonlinear optical systems, the optical superposition principle breaks down. The system’s response (including electric polarization, current density, etc) is not proportional to the stimulus it receives. Over the past half century, nonlinear opti

Constructing ultraviolet nonlinear optical crystals with large second harmonic generation and short absorption edges by using polar tetrahedral S2O3 groups

Autor: Shixian Ke, Huixin Fan, Chensheng Lin, Ning Ye, Min Luo

Publikováno v: Inorganic Chemistry Frontiers. 10:2811-2817

It is generally considered difficult for traditional sulfates to exhibit strong second harmonic generation (SHG) responses and large birefringence values because SO4 groups are nonpolar tetrahedral structures.

Be 2 (BO 3 )(IO 3 ): The First Anion‐mixed Van der Waals Member in the KBe 2 BO 3 F 2 Family with a Very Strong Second Harmonic Generation Response

Publikováno v: Angewandte Chemie. 133:17555-17558

To obtain new nonlinear optical (NLO) materials with a large second harmonic generation (SHG) effect has always been a great challenge. We have synthesized the first metal borate-iodate NLO crystal, Be2 (BO3 )(IO3 ) (BBIO), by multicomponent modifica

Te(CS(NH2)2)4SO4·2H2O: A Three-in-One Semiorganic Nonlinear Optical Crystal with an Unusual Quadrilateral (TeS4)6– Chromophore

Autor: Kaichuang Chen, Min Luo, Ning Ye, Xin Zhao, Huixin Fan, Chensheng Lin, Guang Peng, Xiaoya Weng

Publikováno v: Crystal Growth & Design. 21:2596-2601

The first tellurium(II) thiourea sulfate semiorganic nonlinear optical (NLO) material, Te(CS(NH2)(2))(4)SO4 center dot 2H(2)O, was successfully obtained using the slow evaporation technique. The structure of this metal-free crystal featured three typ

[C(NH2)3]3PO4·2H2O: A new metal-free ultraviolet nonlinear optical phosphate with large birefringence and second-harmonic generation response

Autor: X. J. Wen, Min Luo, Chensheng Lin, Kaichuang Chen, Ning Ye, Huixin Fan

Publikováno v: Science China Materials. 64:2008-2016

[PO4]3− possesses small microscopic second-order susceptibility and polarizability anisotropy, which inherently result in weak second-harmonic generation (SHG) and small birefringence. Herein, a new noncentrosymmetric phosphate, [C(NH2)3]3PO4·2H2O

Ba(IO3)F: An Alkaline-Earth-Metal Iodate Fluoride Crystal with Large Band Gap and Birefringence

Autor: Kaichuang Chen, Ning Ye, Huixin Fan, Chensheng Lin, Shunda Yang, Guang Peng

Publikováno v: Inorganic Chemistry. 59:7376-7379

An alkaline-earth-metal iodate fluoride, Ba(IO3)F (1), was discovered by introducing F atoms into alkaline-earth-metal iodates via a hydrothermal method. The pseudo-two-dimensional (2D) [BaF]+ laye...
