摘要：

Photodegradation has been observed in Tm3+-doped ZBLAN fiber lasers pumped with laser diodes at 3.135 nm. After upconversion lasing at 482 nm, the fiber develops color centers that absorb strongly at wavelengths below similar to 650 nm, affecting further upconversion lasing. The rate of damage formation is strongly dependent on the pump power level and on the thulium concentration. The color centers are bleached by intense blue light but recover with thermal excitation and can be removed by thermal annealing at temperature near 100 degrees C.
