The quencher concentration (c(max)) of rare-earth (RE3+) doped laser glass plays a pivotal role in achieving high laser gain. However, it is still challenging to quantitatively calculate and predict the c(max) of RE3+ ions in laser glass. Here, we propose and demonstrate a robust method in predicting the local environment and the c(max) of RE3+ in laser glasses from their neighboring glassy compounds (NGCs). Specifically, the NGCs method capably predicts the local environment of Er3+ ions in borate glasses (B2O3-BaO binary and B2O3-BaO-Li2O ternary glasses). Moreover, the NGCs' method accurately predicts the c(max) of Er2O3 in borate glasses with an error of less than 5% compared to the experimental result, showing the promising prediction capability for the c(max) of RE3+ ions. Based on the NGCs method, the c(max) database of Er3+-doped borate glasses is established for efficiently tailoring compositions with desired optical properties. This study offers a rapid and low-cost route to design novel laser glasses.
