Broadband 1.0 µm emission in Nd/Yb co-doped phosphate glasses and fibers for photonic applications.

In this work, the spectroscopic properties of 1.0 µm emission in Nd/Yb co-doped phosphate glasses were systematically investigated under 808 nm excitation. Notably, broadband 1.

Broadband near-infrared amplified spontaneous emission of Er-doped germanate glass fiber.

Er-doped glass and fiber are very attractive for near-infrared (NIR) lasers and photonic applications. In this work, the full width at half maximum (FWHM) of NIR fluorescence emission of the Er-doped germanate glass can be broadened from 72 to 99 nm when AlO was added. In addition, the spectroscopic properties, including absorption and emission spectra, Judd-Ofelt intensity parameters, absorption and emission cross sections, gain coefficient, and fluorescence lifetime, of the AlO-modified germanate glass were systematically investigated.

Efficient and Broadband Emission in Dy-Doped Glass-Ceramic Fibers for Tunable Yellow Fiber Laser.

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(WO): Dy glass-ceramic fiber (GCF) for the first time.
