Embodiment 1

[0035] Taking the chemical reaction formula (1) as an example, the specific operation steps are as follows:

[0036] Weigh SrCl with a molar ratio of 1:2:2 2 ·6H 2 O, L(+)-C 4 h 6 o 6 and H 3 BO 3 For solid powder, dissolve it in a container filled with 100mL of deionized water, shake the solution gently, and let it stand for half an hour to dissolve completely. In order to make the solution mix evenly, treat it in ultrasonic waves at a temperature of 30°C for 30 minutes, and finally become clear and transparent;

[0037] Then take out the container containing the solution, let it cool down to room temperature naturally, then add KOH to the solution one by one at a time of 0.1 g, shake the container constantly during the addition process, when the pH value reaches 7, white insoluble particles will appear in the solution Continue to adjust the pH value to 8, stop adding KOH, and treat it in ultrasonic wave for 30 minutes, so that the reaction is sufficient, and the white ...

[0042] Take the chemical reaction formula (1) as an example:

[0043] Weigh SrCl with a molar ratio of 1:2.5:3 2 ·6H 2 O, L(+)-C 4 h 6 o 6 and H 3 BO 3 For solid powder, dissolve it in a container filled with 200mL of deionized water, shake the solution gently, and let it stand for half an hour to dissolve completely. In order to make the dissolution and mixing even, treat it in ultrasonic waves at a temperature of 35°C for 30 minutes, and finally become clear and transparent;

[0044] Then take out the container containing the solution, cool it down to room temperature naturally, then add KOH to the solution one by one at a time of 0.1 g, shake the container constantly during the addition process, when the pH value reaches 7, it is found that white insoluble in the solution begins to appear Continue to adjust the pH value to 9, stop adding KOH, and process in ultrasonic for 30 minutes, so that the reaction is sufficient, and the white insoluble matter is evenly deposite...

[0049] Take the chemical reaction formula (1) as an example:

[0050] Weigh SrCl with a molar ratio of 1:4:10 2 ·6H 2 O, L(+)-C 4 h 6 o 6 and H 3 BO 3 For solid powder, dissolve it in a container filled with 300mL deionized water, shake the solution gently, and let it stand for half an hour to dissolve completely. In order to make the solution mix evenly, treat it in ultrasonic waves at a temperature of 40°C for 30 minutes, and finally become clear and transparent;

[0051] Then take out the container containing the solution, let it cool down to room temperature naturally, then add KOH to the solution one by one about 0.1g each time, shake the container constantly during the addition process, when the pH value reaches 7, the solution begins to appear white For insoluble matter, continue to adjust the pH value to 12, stop adding KOH, and treat it in ultrasonic for 30 minutes, so that the reaction is sufficient, and the white insoluble matter is evenly deposited on the bot...

Description

technical field [0001] The invention relates to an organic-inorganic hybrid compound strontium potassium boron tartrate nonlinear optical crystal, which is prepared by an aqueous solution method, and a nonlinear optical device manufactured by using the crystal. Background technique [0002] As a high-intensity, directional coherent monochromatic light source, laser is widely used in military, scientific research and economic life related fields. However, the current solid-state lasers can only output several wavelengths isolated or with a narrow tuning range, and due to the particularity of the laser generation mechanism, it is impossible to find a practical laser medium for each wavelength. Therefore, the use of nonlinear optical crystals for frequency conversion to obtain various laser sources with wide tuning has become a frontier topic in the development of laser technology. In modern laser technology, frequency conversion crystals, especially frequency doubling crystal...
