According to the radiative lifetime obtained from the Judd-Ofelt parameters and the measured lifetime  the 1.5m quantum efficiency was calculated. The quenching effect of OH upon the lifetime of 1.5m emission was investigated. From the absorption sideband measurement of glass host  the value of optical band gap was estimated. The McCumber theory was used to calculate the stimulated emission cross-section and in approximate agreement with experimental one if the emission spectrum could be obtained accurately. The gain coefficient spectra were computed.
