Abstract

An Er3+/Yb3+ phosphate laser glass was fabricated and characterized. According to McCumber theory, the stimulated emission cross-section of Er3+ ions at 1533 nm calculated by absorption spectrum was 0.84*10^(-20) cm2, and the fluorescence lifetime of 4I_(13/2) level was 8.5 ms. Continuous wave (CW) laser operation of this Er3+/Yb3+ phosphate glass pumped by laser diode (LD) was demonstrated at room temperature. The maximum output power of 80 mW and slope efficiency of 16.5% were obtained.
