摘要：Fabricate the neodymium-doped lithium borate glass. In this paper, the transmission spectrum and the reflection spectrum of the borate glass doped with Nd3+are measured, using TU-1901 UV-Vis Spectrophotometer. There are four absorption peaks (525nm, 580nm, 745nm and 805nm ) between 200nm∼850nm and the absorption cross sections of the peaks are 1.45×10-20cm2, 1.98×10-20cm2, 1.92×10-20cm2, 1.94×10-20cm2. The peaks are similar to the peaks of Nd: YAG in the visible range. The results show that the absorption peaks of the sample are intense and wide. By analyzing the absorption curve, it is found that the transition below the absorption edge corresponds to indirect transition. Furthermore, the band gap Egfor indirect transition is 3.14eV, and the phonon energy Ep. is 180meV. ©2011 IEEE.
