Abstract

We report on a new and versatile technique to fabricate step-index fluoride fibers for laser applications. The fibers made were doped with Tm³⁺ to explore suitability for lasing at 2.3μm. The large mode area fibers with 30μm core diameter exhibit an NA of ~0.04. The propagation loss of the fibers was evaluated in terms of fiber drawing conditions and quality of the interface between core and cladding region in the fibers. Pumping at 790nm, the fluorescence of Tm³⁺ at 2.3μm is stronger than that at 2.0μm, demonstrating potential of the fiber as a 2.3μm laser.
