“…In recent years, yellow lasers (565–590 nm) of Dy 3+ ions doped in glass and fibers have found important applications in Bose–Einstein condensation, visible light communication, medical treatment, and optical thermometry 1–5 . Compared to the well‐developed visible lasers operating at blue, green, and red wavelengths regions, the methods to obtain yellow lasers rely on the dye lasers 6 and the nonlinear methods (containing frequency doubling, 7 sum‐frequency, 8 and four‐wave mixing 9 ). However, the environmentally unfriendly issues, high cost, and complex free‐space system have limited the practical applications of the dye lasers and nonlinear frequency conversions to generate yellow lasers.…”

In this work, we study the mechanisms of X‐ray induced darkening in the Dy/Al/P co‐doped silica glasses at visible wavelengths and explore the role of P/Al ratio played in the enhancement of irradiation resistance. The absorption, emission spectra and lifetime, Raman, and electron paramagnetic resonance spectra of pristine and irradiated Dy‐silica glasses as a function of P/Al ratio were measured and analyzed. The Si‐related defects (Si‐E′ and non‐bridge oxygen hole center), Al‐related defects (Al‐E′ and Al‐related oxygen hole center), P‐related defects (P‐OHC and P2), and Dy2+ ions were studied and analyzed. Results demonstrate that increasing P/Al is efficient to suppress the photodarkening in Dy‐silica glasses at visible wavelengths. Results imply that Dy‐silica glasses with P/Al > 1 may be a promising candidate for efficient visible fiber lasers operated at around 575 nm wavelength.
