掺钕硼酸锂激光玻璃的光学吸收特性
Optical Absorption Characteristic of Nd Doped Lithium Borate Laser Glass
摘要
Abstract
Glass doped with rare earth ions is widely used in the field of nuclear fusion, high-power laser amplifiers and fiber lasers. The refractive index of the neodymium-doped lithium borate glass was measured and investigated by ellipsometry. The transmission spectra and reflection spectra were obtained using a TU-1901 ultraviolet-visible （UV-VIS） spectrophotometer in this work. The refractive index is about 1. 684 and the extinction coefficient is 0. 056 at 632.8nm. The absorption spectrum of the borate glass doped with Nd3＋ was analyzed. There are four absorption peaks which are similar to the absorption peaks of Nd. YAG in the visible range, and the absorption sections of these peaks are 1.45×10-20cm2、1.98×10-20cm2、1.92×10-20cm2、1.94×10-20cm2, respectively.关键词
