Monolithic silica fiber laser operating at 585 nm

We report, to the best of our knowledge, the first monolithic silica fiber laser operating in the visible. The laser cavity is based on a dysprosium-doped aluminosilicate fiber bounded by a pair of fiber Bragg gratings operating at 585 nm. The yellow laser signal reaches a record output power of 147 mW. Although the pump irradiation causes photodarkening, sig-nificant reduction of the photoinduced absorption losses is demonstrated via a photobleaching process with visible light.(c) 2023 Optica Publishing Group

Automated summary

We present the first monolithic silica fiber laser operating in the visible range, which achieves a record output power of 147 mW for the yellow laser signal. Despite photodarkening caused by pump irradiation, we demonstrate a significant reduction in photoinduced absorption losses through a photobleaching process with visible light.
