[0075] It can be understood that multiple sets of relationships between the laser performance data of laser glasses and the content data of the target microstructure units are required to solve the coefficient c to be determined through multiple linear fitting 1~n . In some of these embodiments, multiple linear expressions are constructed from the laser performance data of multiple different laser glasses, the corresponding content data of the target microstructure units, and the coefficient to be determined
[0076] It can be understood that in the above expressions, c in the expressions with different m values 1~n is the same coefficient to be determined, but X m1~mn is only the content data of the target microstructure units of the laser glass G m corresponding to Y m respectively

[0085] Example 1
[0086] This example provides a method for establishing the correlation between the metastructure units and the peak stimulated emission cross-section of the F→I energy level transition in a 4-component Nd-doped phosphate laser glass. 3+ The steps for establishing the correlation between the metastructure units and the luminescence properties of the laser glass are as follows: 4 F 3 / 2 → 4 I 11 / 2 Obtain the component data and laser performance data Y of 20 groups of Nd-doped K2O-La2O3-B2O3-P2O5 laser glasses from the INTERGLAD glass database.
[0087] Based on the component data, obtain the metastable K2O-La2O3-B2O3-P2O5 glass structure data corresponding to different component data by molecular dynamics simulation of the heating and quenching process.
[0088] From the glass structure data, screen out the target metastructure units that describe the glass topological structure. Refer to 3+ for details. In this example, the configurations of the target metastructure units are as shown in 1~20 . The target metastructure units are phospho-oxygen tetrahedra [PO4], borate-oxygen tetrahedra [BO4], borate-oxygen triangles [BO3], bridging oxygen [BO], and non-bridging oxygen [NBO]. e .
[0089] Obtain the content data of the target metastructure units. The content data corresponding to the phospho-oxygen tetrahedron [PO4] is X1, the content data corresponding to the borate-oxygen tetrahedron [BO4] is X2, the content data corresponding to the borate-oxygen triangle [BO3] is X3, the content data corresponding to the bridging oxygen [BO] is X4, and the content data corresponding to the non-bridging oxygen [NBO] is X5.
[0090] Establish a linear relationship expression between the laser performance data, the content data, and the coefficients to be determined for each group: Figure 1 Figure 1 Y1 = c1X
[0091] + c2X
[0092]
[0093] 11 21 Y1 = c1X 11 + c2X 21 + c3X 13 + c4X 14 + c5X15
[0094] Y2 = c1X 21 + c2X 22 + c3X 23 + c4X 24 + c5X 25 ......
[0096] Y 20 = c1X 201 + c2X 202 + c3X 203 + c4X 204 + c5X 205
[0097] It can be understood that in the above expressions of Y (m = 1 to 20), c in the expressions with different m values m is the same coefficient to be determined, but X (m = 1 to 20) is only the content data of the target microstructural unit of the laser glass corresponding to each Y (m = 1 to 20). 1~5 for each Y (m = 1 to 20). m1~m5 (m = 1~20)is only the content data of the target microstructural unit of the laser glass corresponding to each Y m (m = 1 to 20).
[0098] The coefficient c to be determined is solved by multiple linear fitting 1~5 , and the functional relationship between the glass microstructural unit - emission cross - section σ e is obtained: σ e = - 1.46X1 - 0.12X2 + 2.317X3 + 3.01X4 - 0.56X5

[0103] Obtain the component data and laser performance data Y 3+ of 20 groups of Nd - doped K2O - La2O3 - B2O3 - P2O5 laser glass from the INTERGLAD glass database 1~20 . Among them, the laser performance Y is the radiative lifetime τ.
[0104] Based on the component data, the metastable K2O-La2O3-B2O3-P2O5 glass structure data corresponding to different component data are obtained by molecular dynamics simulation of the heating and quenching process.
[0105] Select the target microstructure units that describe the glass topology from the glass structure data. Please refer to Figure 1 , the configurations of the target microstructure units selected in this embodiment are as Figure 1 shown, and the target microstructure units are phosphorus oxygen tetrahedron [PO4], boron oxygen tetrahedron [BO4], boron oxygen triangle [BO3], bridging oxygen [BO] and non-bridging oxygen [NBO].
[0106] Obtain the content data of the target microstructure units. The content data corresponding to the phosphorus oxygen tetrahedron [PO4] is X1, the content data corresponding to the boron oxygen tetrahedron [BO4] is X2, the content data corresponding to the boron oxygen triangle [BO3] is X3, the content data corresponding to the bridging oxygen [BO] is X4, and the content data corresponding to the non-bridging oxygen [NBO] is X5.
[0107] Establish a linear relationship expression between the laser performance data of each group, the content data, and the coefficients to be determined:
[0108] Y1 = c1X 11 + c2X 21 + c3X 13 + c4X 14 + c5X 15
[0109] Y2 = c1X 21 + c2X 22 + c3X 23 + c4X 24 + c5X 25 ......
[0111] Y 20 = c1X 201 + c2X 202 + c3X 203 + c4X 204 + c5X 205
[0112] It can be understood that in the above expressions of Y m (m = 1~20), the c 1~5 in the expressions for different m values are the same coefficients to be determined, but X m1~m5 (m = 1~20) is only the content data of the target microstructure units of the laser glass corresponding to Y m (m = 1~20) respectively.
[0113] Solve the coefficients to be determined c by multiple linear fitting1~5 to obtain the functional relationship of the glass microstructure unit - radiation lifetime τ: τ = 50.13X1 - 23.51X2 + 10.47X3 - 15.37X4 + 23.56X5.
[0114] Test Example 1

For the test results of this test example, please refer to 21~32 Figure 3 , Figure 3 which is the control chart of τ calculated from the functional relationship between the glass microstructure unit and the radiation lifetime τ obtained in Example 2 of this application and the measured τ.
[0118] It can be seen from Figures 2 - 3 that the correlation coefficient R of the functional relationship between the glass microstructure unit - luminescence performance obtained in Examples 1 and 2 is close to 1, indicating that the fitting and prediction effects of the linear model of this application are better and the applicable range is wider. This application can use the microstructure unit describing the glass topological structure to construct a relatively accurate linear model with the glass laser performance, use the linear model to predict the laser performance in a large range of glass composition space, and screen out the laser glass components with excellent laser performance from it, which can realize the research and development of more efficient and low-cost laser glass.
