Germanate glass for 2micron laser output, and preparation method thereof

Номер: CN104140203A
Принадлежит:

The invention discloses germanate glass for 2micron laser output, and a preparation method thereof. The glass comprises the following components: 35-55mol% of GeO2, 5-10mol% of SiO2, 15-35mol% of PbO/PbO4/3, 5-10mol% of ZnO, 5-15mol% of MO/MCO3 (M is alkaline-earth metal Ca, Sr or Ba), and 0.1-2mol% of Re2O3 (Re is one or two of rare-earth ion Tm or Ho). The prepared glass has the characteristics of good heat stability, high infrared transmittance, low hydroxy content, high fluorescence emission strength and high rare-earth ion solubility. The components and the preparation method of the glass are suitable for preparation and application of the 2micron rare-earth doped germanate optical fiber glass material.
