  • Abstract
    Continuous wave (CW) lasing in a thulium-doped fluorozirconate fiber at 1.46 μm with a 20% slope efficiency was observed. Simultaneous lasing at 1.86 μm with 29% slope efficiency depopulates the normally long lived 1.46-μm terminal level. It is shown that the cascade process can increase the slope efficiency ηs, of the 1.45-μm transition by a factor of ten and the 1.86-μm transition by a factor of eight. Calculations indicate that the CW laser thresholds decrease significantly
