Abstract

The invention discloses a preparation method of laser glass glass material with specific laser performance. The method comprises the following steps: forming a glass composition-laser performance database; constructing a composition intelligent design model; dividing the glass composition-laser performance database into a training data set and a test data set, which are respectively used for training and testing the composition intelligent design model, and obtaining The trained component intelligent design model; input the required target laser performance, and filter out the glass composition that meets the target performance through the reverse calculation of the component intelligent design model; prepare laser glass with specific laser performance according to the screened glass formula. The invention is a high-efficiency and low-cost laser glass material preparation method, which greatly speeds up the research and development of laser glass materials.

Description

technical field [0001] The invention belongs to the field of glass material research, and in particular relates to a preparation method of laser glass material with specific laser performance. Background technique [0002] Throughout human history, glass has been one of the most important and influential of all materials, and its importance continues to grow every day. A distinctive feature of glasses is their amorphous structure, which does not need to meet the strict stoichiometric requirements found in crystal chemistry. Therefore, almost every element in the periodic table can be added to glass, so there is an infinite number of potential glass materials, which makes the development of glass materials with specific properties very difficult. The future application of glass materials requires precise and efficient design of its composition formula and performance to meet the functional requirements of different application fields. However, due to the uncertainty of glas...
