Embodiment 1

[0013] A polishing liquid for YAG bonding crystal polishing, by weight percentage, comprising: 1%-2% nitric acid, 10%-15% corundum, 1%-3% diamond powder, 8%-10% of sodium lauryl sulfate, 70%-80% in water.

[0014] The patent can be obtained by mixing all the above-mentioned raw materials.

[0015] The principles and advantages of this patent are as follows: nitric acid is a highly corrosive inorganic acid, which can corrode the crystal surface during the polishing process to speed up the processing process; the composition of corundum is AL2O3, which is a powdery substance like diamond powder. It plays a role in grinding YAG; sodium lauryl sulfate is an anionic surfactant, which is easily soluble in water and has good wetting, flotation, decontamination and foaming properties, and can be well matched with other components in the polishing liquid. Improves the quality of the polished surface; the water is deionized to ensure purity and no impurities.

Embodiment 2

[0017] A polishing liquid for spinel-bonded crystal polishing, by weight percentage, comprising: 0.5%-1% nitric acid, 10%-15% corundum, 1%-2% diamond powder, 15%-20% of sodium lauryl sulfate, 70%-80% in water.

[0018] The patent can be obtained by mixing all the above-mentioned raw materials.

[0019] The principles and advantages of this patent are as follows: nitric acid is a highly corrosive inorganic acid, which can corrode the crystal surface during the polishing process to speed up the processing process; the composition of corundum is AL2O3, which is a powdery substance like diamond powder. It plays a role in grinding YAG; sodium lauryl sulfate is an anionic surfactant, which is easily soluble in water and has good wetting, flotation, decontamination and foaming properties, and can be well matched with other components in the polishing liquid. Improves the quality of the polished surface; the water is deionized to ensure purity and no impurities.

Embodiment 3

[0021] A polishing liquid for YAG bonding crystal polishing, in weight percentage, comprises: 1.5% nitric acid, 13% corundum, 2% diamond powder, 9% sodium lauryl sulfate, 75% water.

[0022] The patent can be obtained by mixing all the above-mentioned raw materials.

[0023] The principles and advantages of this patent are as follows: nitric acid is a highly corrosive inorganic acid, which can corrode the crystal surface during the polishing process to speed up the processing process; the composition of corundum is AL2O3, which is a powdery substance like diamond powder. It plays a role in grinding YAG; sodium lauryl sulfate is an anionic surfactant, which is easily soluble in water and has good wetting, flotation, decontamination and foaming properties, and can be well matched with other components in the polishing liquid.

Abstract

The invention discloses a polishing solution for polishing YAG (yttrium aluminum garnet) bonded crystals and spinel bonded crystals, which comprises the following components in percentage by weight: 0.5 to 2 percent of nitric acid, 10 to 15 percent of corundum, 1 to 3 percent of diamond powder, 8 to 20 percent of sodium lauryl sulfate and 68 to 80 percent of water. All the raw materials are mixed to obtain the traditional Chinese medicine composition. The principle and the advantages of the invention are as follows: nitric acid is a highly corrosive inorganic acid, and can corrode the crystal surface in the polishing process so as to accelerate the processing process; the component of corundum is AL2O3, is a powdery substance like diamond powder, and plays a role in grinding YAG in the polishing process; the sodium lauryl sulfate anionic surfactant is easily soluble in water, has good wetting, floating, decontamination and foaming properties, and can be matched with other components in the polishing solution to well improve the quality of a polished surface; the water is deionized water, so that the water is pure and impurity-free.

Description

technical field [0001] The invention relates to the technical field of polishing liquid preparation, in particular to a polishing liquid used for polishing YAG-bonded crystals and spinel-bonded crystals. Background technique [0002] 1535nm laser has broad market prospects as an eye-safe light source. The cobalt spinel crystal is the core component of this type of laser. [0003] YAG: Yttrium Aluminum Garnet, chemical formula Y3AI5O12, is a man-made compound that does not exist in nature. Yttrium aluminum garnet crystals formed by doping special rare metals during the growth process can be used as laser media. Doping different rare metals produces lasers of different wavelengths. For example, doping Nd (neodymium) can produce 1064nm lasers. Doping Yb (ytterbium) can produce 1030nm wavelength. [0004] Crystal bonding: The technology of directly bonding two homogeneous or heterogeneous crystals with clean surfaces and nano-level flatness through surface cleaning and activa...
