Embodiment 1

[0025] The composition (moles) of the precursor solution is: methyltriethoxysilane (CH 3 Si(OC 2 h 5 ) 3 ) 10±4mol, ethanol 38±5mol, deionized water 40±4mol, pyrrole methylidene 567 (P-567) laser dye 100±50mmol. Dissolve methyltriethoxysilane in ethanol, add the ethanol solution of P-567 laser dye at 20°C to 70°C, stir for 30 to 100 minutes, add deionized water dropwise, and adjust the pH value of the mixture with hydrochloric acid 1 to 4, continue stirring for 2 to 6 hours to hydrolyze vinyltriethoxysilane. Then add alkali polycondensation catalyst 3-aminopropyltriethoxysilane (NH 2 (CH 2 ) 3 Si(OC 2 h 5 ) 3 ), adjust the pH value of the mixture to 4-7, and continue stirring for 1-4 hours. The mixed liquid is left standing in the environment of 30 DEG C to 70 DEG C, and after 10 to 40 days, the P-567 laser dye-doped inorganic-based organic composite solid-state tunable dye laser medium is prepared.

Abstract

The invention discloses a stable inorganic-based organic composite solid-state tunable dye laser medium and a preparation method thereof. The raw materials of the medium are: 5-15 mol of metal alkoxide, 35-45 mol of organic solvent, 30-45 mol of deionized water, and 30-180 mmol of organic laser dye. The steps of the preparation method are: 1) Component design and determination of precursors: metal alkoxides with small organic groups are selected as precursors of organically modified inorganic substrates, inorganic acids are hydrolysis catalysts, and organic solvents are selected as solvents , the metal alkoxide containing aminopropyl group is the alkali polycondensation catalyst, and the organic laser dye is the laser active substance; 2) The step-by-step synthesis and preparation of the inorganic-based organic composite solid-state tunable dye laser medium. The invention can obtain an optically uniform solid-state tunable dye laser medium with controllable microstructure and molecular level recombination. The composition and structure of the medium are uniform, the optical transparency in the ultraviolet and visible bands is good, the heat dissipation performance of the material is improved, and the laser output life of the composite solid-state dye laser medium is significantly improved.

Description

technical field [0001] The invention relates to a stable inorganic-based organic composite solid-state tunable dye laser medium. Background technique [0002] Tunable dye lasers have a wide tunable range, and the laser emission of different dyes can cover the entire band of ultraviolet, visible and even near-infrared; the efficiency of visible light band is high. However, compared with solid-state laser systems, the current commercial liquid tunable dye lasers have disadvantages such as complex structure, poor operation reliability, and troublesome maintenance. The dye replacement procedure is also very cumbersome, and a large amount of toxic, flammable and explosive waste liquid will be generated every time it is replaced. Therefore, although liquid tunable dye lasers can be used in scientific research (spectroscopy), medical treatment (tissue optics, diagnosis, treatment), military (laser guidance, communication, electro-optical interference) and othe...
