“…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.

“…Nowadays, yellow light lasers operating at 565-590 nm have attracted extensive attention in various fields, for example, in the biomedical area, where yellow light lasers can be used for the treatment of vascular diseases due to hemoglobin's high absorption of yellow light at wavelengths [1][2][3]. However, the output of a yellow laser is relatively difficult, since it is mainly based on high maintenance dye lasers or complex nonlinear frequency transformations such as a sum frequency generation [4], frequency doubling [5], four-wave mixing [6] and Raman conversion [7]. By contrast, direct access of a yellow laser by using a laser diode (LD) to pump rare-earth (RE)-ion doped fibers can leave out the complicated nonlinear optical processes for higher integration and has a high heat dissipation performance.…”

Yellow lasers are of great interest in biology, medicine and display technology. However, nonlinear emission of near-infrared lasers at yellow still presents particularly complex optical alignment to date. Here, to the best of our knowledge, we demonstrate the fabrication of a NaLa(WO4)2: Dy3+ glass-ceramic fiber (GCF) for the first time. More importantly, the emission band of the GCF, which is around 575 nm, has a wide full-width half maximum (FWHM) of 18~22 nm, which is remarkably larger than that of the Dy3+-doped YAG crystal (<7 nm). The precursor fiber (PF) was drawn using the molten core drawing (MCD) method. In particular, benefiting from the in situ nanocrystals fabricated in the amorphous fiber core after thermal treatment, the resultant glass-ceramic fiber exhibits a five-times enhancement of luminescence intensity around 575 nm, compared with the precursor fiber, while retaining its broadband emission. Overall, this work is anticipated to offer a high potential GCF with prominent bandwidth for the direct access of a tunable yellow laser.

“…The output spectrum extended from 390 to 2400 nm with good flatness. The other way is to directly generate SC in the nonlinear fiber amplifier [15][16][17][18] . It usually employs a high peak-power pulsed laser as the seed laser for injection into the fiber amplifier, in which the laser peak power can be boosted and induce the strong nonlinear effects to realize SC output.…”

The generation of supercontinuum (SC) often requires ultrashort pulsed lasers with high peak power and gain media with large nonlinear coefficients, such as a long piece of fiber or photonic crystal fiber. In this Letter, we propose and demonstrate that high-power SC can be generated through a simple narrow-bandwidth fiber Bragg gratings (FBGs)-based laser cavity without any modulation, based on the mechanism of intense nonlinear effects induced by the inherent self-pulsation generated inside the cavity. In the experiment, an ∼80 W SC laser with the spectrum range from < 600 nm to 1600 nm was achieved. To the best of our knowledge, this is the first report about SC generation through a simple fiber laser cavity. This work enriches the research content of SC and provides a cost-effective method for high-power SC lasers.
