title: Optical absorption and near infrared emissions of Nd3+ doped fluorophosphate glass.
abstract: Fluorophosphate glass doped with Nd(3+) has been synthesized with low OH content. Near infrared emissions centered around 0.9, 1.06, and 1.3 μm have been successfully obtained in present glass excited by a conventional 800 nm laser diode. Based on the absorption spectrum, radiative properties were calculated and discussed using the Judd-Ofelt theory. The luminescence characteristics and energy transfer mechanism were investigated. Desirable low OH(-) concentration and spectroscopic characteristics of Nd(3+)-doped fluorophosphate glass indicate that it is a promising material for near-infrared lasers.
