Description

Method, device and computer equipment for predicting rare earth quenching concentration in laser glass Technical Field

[0001] The present disclosure relates to the technical field of glass materials, and in particular to a method, device, and computer equipment for predicting rare earth quenching concentration in laser glass. Background Art

[0002] Glass is an inorganic material with extremely wide applications. In addition to being used in common consumer goods, construction, chemicals, and medical fields, it is also widely used in numerous high-tech fields, including electronics and information technology, defense and military industry, transportation, and energy. Laser glass, a solid-state laser material with a glass matrix, serves as the core gain medium for solid-state lasers and fiber lasers. Laser glass is typically doped with rare earth metal ions, and the concentration of these ions is a key parameter in determining the gain characteristics of laser glass.

[0003] Generally, increasing the rare earth metal doping concentration in laser glass increases the number of excited upper energy level particles, thereby improving laser output power and slope efficiency. It also helps shorten the laser cavity length, facilitating device miniaturization and intensification. However, when the doping concentration reaches a certain value, the excessively strong interactions between ions increase energy transfer processes such as cross-relaxation, leading to a decrease in upper energy level lifetime and luminescence intensity. Furthermore, it can also cause the glass to undergo phase separation or crystallization, reducing the solubility of rare earth metal ions in the glass matrix. Due to the combined effects of these two factors, the luminescence intensity of laser glass increases first and then decreases with increasing doping concentration. This indicates that there is an optimal rare earth doping concentration corresponding to the maximum luminescence intensity of the laser glass, known as the rare earth quenching concentration in the laser glass. Traditional techniques typically require a series of experiments with varying doping concentration gradients to ultimately determine the rare earth quenching concentration in laser glass. Changes to the glass substrate or the doped rare earth metal ions require repeated experiments to determine the rare earth quenching concentration. This method suffers from long cycle times, low efficiency, and high costs, limiting the further development of laser glass.

[0037] FIG1 is a method for predicting the rare earth quenching concentration in laser glass according to the present disclosure. Referring to FIG1 , the prediction method includes steps S1 to S3, which are specifically as follows.

[0038] Step S1: obtaining a target laser glass, taking compounds that can be composed of elements of various oxide components in the target laser glass as candidate compounds, and selecting adjacent compounds from the candidate compounds.

[0039] The target laser glass contains a glass matrix and rare earth metal ions. The glass matrix is ​​typically composed of one or more oxide components, and the glass matrix can be expressed as a combination of oxides. The elements of each oxide component refer to the elements in all oxides that make up the glass matrix. For example, when the laser glass matrix material is barium-boron glass, the oxide components are boron, barium, and oxygen. Alternatively, when the laser glass matrix material is lithium-boron-barium glass, the oxide components are boron, barium, lithium, and oxygen.

[0040] In some examples of this embodiment, the target laser glass is a multi-component oxide glass, that is, the glass matrix of the target laser glass contains multiple oxide components, and the target laser glass is doped with a rare earth metal ion.

[0041] In some examples of this embodiment, the rare earth metal ion is selected from Nd3+ 、Yb 3+ 、Er 3+ 、Tm 3+ 、Ho 3+ 、Pr 3+ 、Eu 3+ 、Sm 3+ 、Ce 3+ 、Dy 3+ and Tb 3+ One of them.

[0042] In some examples of this embodiment, the oxide component of the laser glass contains multiple elements that can form oxides with oxygen, that is, in addition to oxygen, the glass matrix of the laser glass also contains two or more elements.

[0043] In some examples of this embodiment, the step of obtaining candidate compounds includes: calculating the formation energies of various atomic combinations of the matrix elements of the target laser glass based on first principles, and screening atomic combinations with formation energies less than 0 using a particle swarm optimization algorithm as candidate compounds. It will be understood that the various atoms of the matrix elements can form many compounds with different stoichiometric ratios. The purpose of calculating their formation energies based on first principles and screening atomic combinations with formation energies less than 0 is to ensure that the candidate compounds can be spontaneously formed from the matrix elements and exist stably, thereby enabling the quenching concentration of the rare earth element therein to be determined in subsequent steps.

[0044] In some examples of this embodiment, the candidate compound may be a composite oxide, that is, the candidate compound contains multiple elements that can form oxides with oxygen, that is, in addition to oxygen, the candidate compound also contains two or more elements.

[0045] In some examples of this embodiment, the oxide components in the target laser glass are barium oxide and boron oxide, and the matrix components are barium, boron and oxygen. According to the first principle calculation and the screening of the particle swarm optimization algorithm, it can be obtained that BaB2O4, BaB4O7 and BaB8O 13 To form an atomic combination with an energy less than 0, the candidate compounds are BaB2O4, BaB4O7 and BaB8O 13 .

[0046] In some examples of this embodiment, the oxide components in the target laser glass are lithium oxide, barium oxide and boron oxide, wherein the matrix components are barium, boron, lithium and oxygen. According to the first principle calculation and the screening of the particle swarm optimization algorithm, it can be obtained that BaB2O4, BaB4O7, BaB8O 13 、Ba2LiB5O 10 、BaLiB9O15 、Li3B 11 O 18 、Li3B7O 12 , LiB3O5, Li2B4O7 and LiBO2 are atomic combinations with formation energy less than 0, so the candidate compounds are BaB2O4, BaB4O7, BaB8O 13 、Ba2LiB5O 10 、BaLiB9O 15 、Li3B 11 O 18 、Li3B7O 12 , LiB3O5, Li2B4O7 and LiBO2.

[0047] In some examples of this embodiment, the step of selecting at least one neighboring compound from the candidate compounds includes: based on the content of each oxide component in the target laser glass and the content in the candidate compounds, selecting one or more candidate compounds that are closest to the content of each oxide component in the target laser glass as the neighboring compound.

[0048] The purpose of selecting neighboring compounds from the candidate compounds is to screen out candidate compounds with oxide compositions that are closer to the target laser glass. This allows the structures of the selected neighboring compounds to be closer to the "structural elements" of the target laser glass, thereby improving the accuracy of the prediction results. Furthermore, the content refers to the amount of the substance.

[0049] In some examples of this embodiment, a plurality of adjacent compounds may be selected from the candidate compounds. For example, the number of adjacent compounds may be two, three, or more than three.

[0050] For the convenience of calculation, in this embodiment, it is assumed that the target laser glass contains m oxide components, and the content of the i-th oxide component in the target laser glass is recorded as a. i (1≤i≤m)). Then the contents of each oxide component in the target laser glass are recorded as a1~a m For example, assuming that the target laser glass contains two oxide components, the contents of the two oxide components in the target laser glass can be recorded as a1 and a2, respectively. assuming that the target laser glass contains three oxide components, the contents of the three oxide components in the target laser glass can be recorded as a1, a2, and a3, respectively.

[0051] In some examples of this embodiment, the step of selecting adjacent compounds from the candidate compounds is as follows: obtaining the content of each corresponding oxide component in the candidate compound, and the content of the i-th oxide component in the candidate compound is recorded as b i, then the content of each oxide component in an alternative compound can be recorded as b1~b m Then, the metric parameter d of each candidate compound can be calculated by formula (1), and one or more candidate compounds with the smallest d value are taken as neighboring compounds.

[0052] The calculation method shown in formula (1) can quantitatively and accurately characterize the difference between the overall oxide content in the candidate compound and the target laser glass. The smaller the d value, the closer the overall oxide content of the candidate compound and the target laser glass is, and the more accurate the prediction result.

[0053] Furthermore, in some examples of this embodiment, when selecting candidate compounds as neighboring compounds, a measurement threshold may be preset, and candidate compounds having a measurement parameter d value smaller than the measurement threshold are selected as neighboring compounds.

[0054] Step S2: establishing a composition relationship between the adjacent compound and the target laser glass.

[0055] The compositional relationship includes the content of each adjacent compound required to form the oxide composition of the target laser glass. In this prediction method, the adjacent compounds selected in step S1 are used as the "structural elements" of the target laser glass. Accordingly, by matching the content of different adjacent compounds, the content of each oxide component can be made to be the same as the content of each oxide component of the target laser glass.

[0056] In some examples of this embodiment, the step of establishing a compositional relationship between the adjacent compound and the target laser glass includes: the number of the adjacent compounds is n, each adjacent compound is marked from 1 to n, and the content of the i-th oxide component in the j-th adjacent compound is recorded as b ij (1≤j≤n). The content of the i-th neighboring compound required to form the oxide component contained in the target laser glass is recorded as x i The content of each adjacent compound is calculated by formula (2);

[0057] It can be understood that formula (2) represents a matrix operation, where b 11 ~b m1 Indicates the content of each oxide component in the first neighboring compound, b 1n ~b mn represents the content of each oxide component in the mth neighboring compound, x1~x n In the matrix operation shown in formula (2), b ij It can be directly obtained according to the chemical formula of each adjacent compound, ai It can be directly obtained according to the oxide components contained in the target laser glass, then x1~x n It can be obtained by calculation using formula (2).

[0058] Step S3 , performing weighted calculation based on the content of each adjacent compound and the quenching concentration of the rare earth element in each adjacent compound to obtain the predicted quenching concentration of the rare earth element in the target laser glass.

[0059] In this embodiment, "weighted calculation" refers to using the content of each adjacent compound in the composition relationship as a weight, and multiplying the weight by the quenching concentration of the rare earth element in the corresponding adjacent compound, and then performing a sum calculation, so as to obtain the predicted quenching concentration of the rare earth element in the target laser glass.

[0060] In some examples of this embodiment, the quenching concentration of the rare earth element in the neighboring compound is obtained by methods including but not limited to: preparing a rare earth element-doped neighboring compound and obtaining it through testing, obtaining it by consulting literature, and obtaining it by inferring it based on existing results.

[0061] In some examples of this embodiment, the quenching concentration of the rare earth element in the jth neighboring compound is c j And the predicted quenching concentration c of rare earth elements in the target laser glass is obtained by formula (3) * :

[0062] It can be understood that c* is the predicted value of the rare earth element in the target laser glass. For example, when there are two adjacent compounds, n is 2, then the predicted quenching concentration c of the rare earth element in the target laser glass is * =x1c1+x2c2.

[0063] It can be understood that the prediction method of steps S1 to S3 can accurately predict the quenching concentration of rare earth elements in various laser glasses by simply obtaining the quenching concentrations of rare earth elements in a few neighboring compounds as a basis. Furthermore, when the quenching concentrations of rare earth elements in neighboring compounds are all known, this prediction method can relatively accurately derive the predicted quenching concentration of rare earth elements in laser glasses through a simple calculation process.

[0064] The present disclosure provides a method for predicting the rare earth quenching concentration in laser glass. This method uses a weighted calculation based on the content of each neighboring compound and the quenching concentration of the rare earth element in the neighboring compound to obtain the predicted quenching concentration of the rare earth element in the target laser glass. This method cleverly applies the research concept of material genes to laser glass research, creatively proposing the concept of using relatively simple neighboring compounds as "structural elements" for more complex laser glasses. The quenching concentration of the rare earth element in the target laser glass is predicted based on the content of the neighboring compounds and the quenching concentration of the rare earth element in the neighboring compounds. The error between the predicted quenching concentration and the actual quenching concentration is low, and the prediction results are relatively accurate. Furthermore, this prediction method is applicable to a variety of laser glass systems and can be further expanded to other laser glass systems, enabling the prediction of rare earth quenching concentration across the entire glass composition space. This method can effectively improve the efficiency of obtaining rare earth quenching concentration, shorten the cycle time for obtaining rare earth quenching concentration, and reduce costs.

[0065] Furthermore, as shown in FIG2 , the present disclosure also provides a device for predicting rare earth quenching concentration in laser glass, which includes:

[0066] The candidate compound acquisition module 110 is used to acquire compounds that can be composed of elements of various oxide components in the target laser glass as candidate compounds;

[0067] A neighboring compound selection module 120 is used to select neighboring compounds from candidate compounds;

[0068] A composition relationship calculation module 130 is used to establish a composition relationship between the adjacent compounds and the target laser glass, wherein the composition relationship includes the content of each adjacent compound required to form the oxide component of the target laser glass;

[0069] And, the quenching concentration calculation module 140 is used to perform weighted calculation based on the content of each adjacent compound and the quenching concentration of the rare earth element in each adjacent compound to obtain the predicted quenching concentration of the rare earth element in the target laser glass.

[0070] In some examples of this embodiment, the candidate compound acquisition module 110 can be used to calculate the formation energy of various atomic combinations in the matrix constituent elements of the target laser glass through first principles, and screen out atomic combinations with formation energy less than 0 as candidate compounds through a particle swarm optimization algorithm.

[0071] In some examples of this embodiment, the neighboring compound selection module 120 may be configured to calculate the metric parameters of each candidate compound according to the above formula (1), and select neighboring compounds according to the calculated metric parameters.

[0072] In some examples of this embodiment, the composition relationship calculation module 130 can be used to calculate the content of each adjacent compound required to constitute the oxide component contained in the target laser glass according to the above formula (2).

[0073] In some examples of this embodiment, the quenching concentration calculation module 140 can be used to calculate the predicted value of the quenching concentration of the rare earth element in the target laser glass according to the above formula (3).
