“…Therefore, in this work we have applied an alternative SBS suppression technique by using multicomponent phosphate fibers. Thanks to their high solubility of RE ions and weak ionion interactions [24,25], multicomponent phosphate glasses can be doped with large amounts of RE ions (up to 10 21 ions cm −3 ) without clustering [26,27]. This enables the realization of an active medium with a high optical gain in a short length and thus the mitigation of nonlinear optical effects [28].…”

High-power, single-frequency, pulsed fiber amplifiers are required in light detection and ranging, coherent laser detection, and remote sensing applications to reach long range within a short acquisition time. However, the power-scaling of these amplifiers is limited by nonlinearities generated in the optical fibers, in particular by stimulated Brillouin scattering (SBS). In this regard, the use of multicomponent phosphate glasses maximizes the energy extraction and minimizes nonlinearities. Here, we present the development of a single-stage, hybrid, pulsed fiber amplifier using a custom-made multicomponent Yb-doped phosphate fiber. The performance of the phosphate fiber was compared to a commercial Yb-doped silica fiber. While the latter showed SBS limitation at nearly 6.5 kW for 40 cm length, the maximum achieved output peak power for the multicomponent Yb-doped phosphate fiber was 11.7 kW for 9 ns pulses using only 20 cm with no sign of SBS.

“…In optoelectronic applications, phosphate glass systems are of great interest due to their broad optical transmission window and high composition flexibility, in particular in terms of high rare earth ions solubility for lasers. 1,2 In the biomedical field, glasses with different compositions are employed for various applications. 3 Among them, calcium-phosphate glasses have already gained a well-established position especially as a scaffold in both soft and hard tissue engineering.…”

The steps toward the fabrication of directly extruded microstructured fiber preforms made of a bioresorbable phosphate glass are herein presented, analyzing the features of the process from the glass synthesis to the manufacturing of the fiber. The realization of these fibers leverages on three main pillars: an optically transparent bioresorbable glass, its extrusion into a preform, and the fiber drawing. The glass has been designed and carefully prepared in our laboratory to be dissolvable in a biological fluid while being optically transparent and suitable for both preform extrusion and fiber drawing. To support the production of an optimized die for the preform extrusion, a simplified laminar flow model simulation has been employed. This model is intended as a tool for a fast and reliable way to catch the complex behavior of glass flow during each extrusion and can be regarded as an effective design guide for the dies to fulfill the specific needs for preform fabrication. After die optimization, extrusion of a capillary was realized, and a stacking of extruded tubes was drawn to produce a microstructured optical fiber made of bioresorbable phosphate glass.
