Abstract

The invention relates to an intermediate infrared optical doubling frequency crystal fluorinated tungsten potassium iodate material as well as preparation and application thereof. The chemical formulaof the intermediate infrared optical doubling frequency crystal fluorinated tungsten potassium iodate material is K5(W3O9F4)(IO3); the intermediate infrared optical doubling frequency crystal fluorinated tungsten potassium iodate material belongs to a monoclinic crystal system, and has a space group of Pm, and cell parameters (a is equal to 9.7 to 9.8 angstrom, be is equal to 3.7 to 3.8 angstrom,and c is equal to 10.9 to 11.0 angstrom); alpha and gamma are equal to 90 degrees, beta is equal to 101.9 to 102.8 degrees, and Z is equal to 1; cell volume V is 381 to 401 angstrom. Compared with the prior art, the intermediate infrared optical doubling frequency crystal fluorinated tungsten potassium iodate material disclosed by the invention has the advantages that under the irradiation of 1064nm laser, frequency doubling effect strength of powder is about 11 times that of potassium dihydrogen phosphate crystal; under the irradiation of 2.10mu m, the measured frequency doubling effect strength of the powder is equivalent to that of potassium titanium oxide phosphate. Under the laser with the wavelength of 1064nm, a measured laser-damaged threshold of the powder is 95 times that of commercialized infrared second-order nonlinear materials silver, gallium and sulfide; the crystal material has wide transparent range in visible light and an infrared region; a transmittance waveband is 0.32 to 10.5mu m; the intermediate infrared optical doubling frequency crystal fluorinated tungsten potassium iodate material has broad application range in the fields of laser frequency conversion, electrooptical modulation, laser signal holographic storage and the like.

AI Technical Summary

Benefits of technology

This patented technology improves upon existing methods by adding another type of element called magnetic nanoparticles (MNP) into an organic compound containing silver salt or iron oxide. These MNP particles have unique properties such as being able to absorb energy from specific frequencies when exposed to certain types of radiation. By doing this they help improve the efficiency of converting electrical signals between different colors.

Problems solved by technology

This patents describes different types of nonlinear optoelectrooptic crystal compounds called Bragg mirror elements or LC filters due to its ability to generate two waves simultaneously: one wave having higher frequencies than another wave without losing energy when passing through certain media like air. These devices find use in various technical areas including imaging systems, communications, radar, security cameras, biomedical diagnoses, medicine treatments, lasers, and many others.
