Paper Abstract

The intensity parameters are calculated according to the absorption spectra, from which we can know that the host characteristics are not the same for the two types of glasses. Some important parameters such as absorption cross section and integrated emission cross-section are also calculated. Fluorescence spectra near 1540 nm are measured too. We have designed the resonator carefully, with a 969 nm LD to pump the two types of 1.5 mm-thick-Er:Yb:glasses. More than 5.0 mW laser output is obtained and the central wavelength is 1536 nm, with spectra range of about 30 nm. The experiments show that the new type of glass has a better thermal characteristic, and no obvious saturation phenomena appears.
