The Judd-Ofelt intensity parameter Omega(t) of a novel Er3+ doped high silica glass was calculated. The large values Of Omega(2.6) ( Omega(2) 8.15 x 10(-20), Omega(6) = 1.22 x 10(-20)) indicate that the local structure of Er3+ has higher asymmetry and lower covalency than other oxide glasses. McCumber theory was used to calculate the stimulated emission cross section of I-4(13/2) -> I-4(15/2) transition, the result was 0.51 pm(2). Despite the Er3+ -doped concentration in high silica glass being about ten times greater than that in silica fiber, its fluorescence lifetime and quantum efficiency were 6.0ms and 66.0%, respectively. This novel Er3+ -doped glass can be used in optical amplification and microchip laser.
