Pump quantum efficiency optimization of 3.5 μm Er-doped ZBLAN fiber laser for high-power operation
Abstract 976 nm + 1976 nm dual-wavelength pumped Er-doped ZBLAN fiber lasers are generally accepted as the preferred solution for achieving 3.5 μm lasing. However, the 2 μm band excited state absorption from the upper lasing level (4F9/2 → 4F7/2) depletes the Er ions population inversion, reducing t...
