Abstract

The invention relates to a second-order nonlinear optical crystal aluminophosphate as well as a preparation method and application thereof. The chemical formula of the aluminophosphate is Li3Al (PO4) 2 (H2O) 2.5, and the aluminophosphate is in a tetragonal system. According to the invention, phosphate and aluminate are compounded by utilizing a low-temperature hydrothermal preparation method to obtain phosphoaluminate which has a novel structure and is crystallized in a non-central space group, the phosphoaluminate has excellent second-order nonlinear optical performance, the second-order nonlinear optical effect of the powder is about 0.21 time of KH2PO4 (KDP), and the ultraviolet absorption cutoff edge is 380nm.

Description

technical field [0001] The invention belongs to the technical field of second-order nonlinear optical materials, and in particular relates to a second-order nonlinear optical crystal aluminophosphate and its preparation method and application. Background technique [0002] Nonlinear Optics (NLO) refers to various nonlinear material responses that occur when intense light interacts with materials. Although the field has grown with the advent of lasers, nonlinear optical effects play a crucial role in the lasers themselves and dominate their properties. Nonlinear optics is also an important branch of modern optics, studying the nonlinear effects produced by the interaction between laser light and various substances. Nonlinear optics is used in laser intensity control (all-optical switch, light confinement), pulse-spirit compression, frequency-to-frequency conversion (frequency doubling, sum frequency, four-wave mixing), laser spectroscopy (hyperfine structure analysis), and d...
